FAMILY 09 · RACK-MOUNTED HIGH-VOLTAGE · 6 MODELS
Rack-mounted High-Voltage Battery, 30.72 to 209 kWh, 307 to 666 V
A rack of 51.2 V modules in series, with one BMS and one CAN link to the PCS you already own. Six to nine modules of the 100 Ah body gives 30.72 to 46.08 kWh; seven and thirteen of the 314 Ah body gives 112.5 and 209 kWh. Indoor, IP20, no cabinet around it.

WHO THIS IS FOR
For the integrator who already has the PCS
This is a battery, not a system. There is no PCS, no transformer, no fire suppression and no enclosure. You bring the conversion equipment and the rack room; we bring a string of 51.2 V modules with one BMS and a CAN port. That is why a rack is cheaper per kWh than a cabinet, and why it is the wrong product for anyone who wants to buy a finished installation.
It suits EPCs and integrators building a plant room around a third-party PCS, telecom and weak-current rooms that need 30 to 46 kWh at a modest 100 A, and shops or small industry that want two hours of storage at 50 to 100 kW.
It does not suit: an outdoor site, because IP20 means a room; a customer who needs the battery and the inverter in one purchase, because the PCS is not in this price; and any design that assumes the full 209 kW, because 200 A caps the big rack at 133 kW. That last point is the one that ruins quotes, and it has a whole section below.
Nine modules, 46.08 kWh at 460.8 V. The same rack takes six to nine of this module body.
THE SIX MODELS
Two module bodies, six rack heights
Every model is 51.2 V modules in series, one pack per module, and no parallel strings. The 100 Ah body is 5.12 kWh and takes six to nine of them; the 314 Ah body is 16.08 kWh and appears at seven and thirteen. Voltage is simply the module count times 51.2.

Discharge cut-off is 2.8 V per cell and charge cut-off 3.6 V, which is the range printed as discharge and charge voltage on each model. Recommended depth of discharge 90 percent. Working temperature −10 to 50 °C, humidity 5 to 85 percent, IP20, CAN and RS485 to the inverter.
One module: 51.2 V, 100 Ah, 5.12 kWh. Six of these make the smallest rack, nine the largest.
THE NUMBER THAT BREAKS QUOTES
209 kWh does not mean 209 kW
A PCS is sized on power, and on this family the energy and the power happen to be equal on paper. They are not equal in the hardware. The BMS stops at 200 A, so the pair of large models deliver 64 percent of their kWh as kW.
| Model | Catalogue power | Current limit × voltage | Real maximum | Overstated by |
|---|---|---|---|---|
| HV-307V100AH | 30.72 kW | 100 A × 307.2 V | 30.72 kW | Correct |
| HV-358V100AH | 35.84 kW | 100 A × 358.4 V | 35.84 kW | Correct |
| HV-409V100AH | 40.96 kW | 100 A × 409.6 V | 40.96 kW | Correct |
| HV-460V100AH | 46.08 kW | 100 A × 460.8 V | 46.08 kW | Correct |
| HV-358V314AH | 112.5 kW | 200 A × 358.4 V | 71.7 kW | 57 percent high |
| HV-665V314AH | 209 kW | 200 A × 665.6 V | 133 kW | 57 percent high |
WHAT IT MEANS FOR A QUOTE
Pair the 665.6 V rack with a 200 kW PCS and the system will clamp at 133 kW under load. The customer notices on the first hot afternoon, not in the factory test, because the factory test runs at a fraction of rated power.
WHAT IT MEANS FOR SIZING
For a 2-hour application the pair works: 188 kWh usable at 90 kW is inside the 133 kW ceiling. For a 1-hour application it does not, and the honest answer is two racks in parallel or a move up to the 261 kWh cabinet.
WHAT WE ARE DOING ABOUT IT
This page is right and the catalogue is wrong. Ask us for the BMS continuous discharge rating for the 314 Ah module in writing, and quote from that figure until the datasheet is reprinted.
TWO MODULE BODIES
Same voltage, three times the energy
The 358.4 V rack exists twice: seven 100 Ah modules at 35.84 kWh, and seven 314 Ah modules at 112.5 kWh. Same voltage, same module count, same BMS topology. The only difference is the cell inside the module and the current the BMS will pass.
| 100 Ah body | 314 Ah body | |
|---|---|---|
| Module energy | 5.12 kWh | 16.08 kWh |
| Maximum current | 100 A | 200 A |
| C-rate at maximum | 1C | 0.64C |
| Modules in the range | 6, 7, 8, 9 | 7, 13 |
| Energy in the range | 30.72 to 46.08 kWh | 112.5 and 209 kWh |
| Power in the range | 30.72 to 46.08 kW | 71.7 and 133 kW |
| Best for | Telecom, weak-current rooms, small shops | Peak shaving, plant rooms, PCS-based projects |
Do not mix the two bodies in one string. The BMS is built around one module capacity, so a rack is either all 100 Ah or all 314 Ah. Two racks of different bodies can sit side by side on separate PCS inputs, and that is usually the cheaper way to reach 160 kWh than one oversized string.
INVERTER AND PCS COMPATIBILITY
Check the charge voltage, not the brand list
Our compatibility list is DEYE, Solis, Growatt, ATESS, Goodwe and Megarevo, tested on CAN and RS485. That list is necessary and not sufficient, because a rack at 665.6 V puts 748.8 V on the DC bus at full charge and most residential hybrids stop well below that.
| Model | Nominal | At full charge | At cut-off | What it typically pairs with |
|---|---|---|---|---|
| HV-307V100AH | 307.2 V | 345.6 V | 268.8 V | Three-phase hybrid, 350 V input |
| HV-358V100AH | 358.4 V | 403.2 V | 313.6 V | Three-phase hybrid, 410 V input |
| HV-409V100AH | 409.6 V | 460.8 V | 358.4 V | Three-phase hybrid, 470 V input |
| HV-460V100AH | 460.8 V | 518.4 V | 403.2 V | Three-phase hybrid or small PCS, 520 V |
| HV-358V314AH | 358.4 V | 403.2 V | 313.6 V | Same window as the seven-module 100 Ah rack |
| HV-665V314AH | 665.6 V | 748.8 V | 582.4 V | PCS with a 750 V or 800 V DC bus |
The catalogue’s “compatible with residential single and three phase inverters” line sits on both pages, copied from the home product. It is fair for the four 100 Ah racks and misleading for the 665.6 V one, which belongs on a PCS bus. Send us the converter model and we confirm the window in writing.
THE GAPS IN THE DATASHEET
Three numbers an installer needs that we do not print
A rack is bought to fit a room. The two pages give electrical data in detail and say nothing about the rack itself, which is the opposite of what a plant-room designer needs first.
RACK DIMENSIONS
Width, height and depth per model are not printed. Without them nobody can confirm a 19-inch frame, a door swing or a cable bend radius. Ask us for the drawing before you quote a room.
WEIGHT
No module weight, no rack weight. A 209 kWh rack is a floor-loading question and a freight question on the same day, and both need a number we currently do not have on paper.
ALTITUDE
The stacked tower prints 4,000 m and the cabinets print their derating. These two pages print nothing, so do not assume 4,000 m carries over to a rack with a different cooling path.
CYCLE LIFE, IN FULL
6,000 cycles, and the conditions attached to them
The datasheet prints 25±2 °C, 0.2C/0.2C, EOL 70 percent, ≥6,000 cycles. All four conditions matter, and only one of them is usually quoted.
| Condition | What it means in practice |
|---|---|
| 0.2C charge and discharge | 20 A on a 100 Ah module. Run the rack at 100 A every day and the cycle count will not reach 6,000; a peak-shaving duty cycle at 1C is a different life. |
| 25 ± 2 °C | A plant room in the Gulf runs at 35 to 40 °C in summer. Every degree above 25 shortens calendar life, and no datasheet row covers it. |
| EOL at 70 percent | End of life means 70 percent of original capacity, not 80. This is a harder target than most competitors publish and it is worth pointing out to a technical buyer. |
| 90 percent DoD recommended | Usable energy is 90 percent of rated, which is the figure used in every example on this page. |
TYPICAL CONFIGURATIONS
Three builds, with the current checked
Examples, not guarantees. Each one keeps the discharge current under the BMS limit and uses 90 percent depth of discharge.
01 · PEAK SHAVING, 100 kW PCS
209 kWh · 665.6 V
188 kWh usable gives 1.9 hours at 100 kW. Discharge current is 150 A, inside the 200 A limit, so this build is honest. A 1-hour duty at 130 kW is right at the ceiling and leaves nothing for a cooler day.
Needs a PCS whose DC bus accepts 748.8 V.
02 · SHOP WITH A 50 kW PCS
112.5 kWh · 358.4 V
101 kWh usable is two hours at 50 kW. Current is 139 A against the 200 A limit, so there is headroom for the 71.7 kW peak this rack can actually deliver when a compressor starts.
403.2 V at full charge, which most three-phase hybrids accept.
03 · TELECOM OR WEAK-CURRENT ROOM
30.72 kWh · 307.2 V
27.6 kWh usable at 5 kW of base load is five and a half hours, or about 20 hours at the 1.4 kW a small site actually draws. Current is 16 A against a 100 A limit, so the rack is barely working.
The build to specify when the load is small and the room is tight.
Three racks and a PCS on one wall. The rack is one line item in the room, not the room.
BUYING INFORMATION
What the order actually looks like
| Minimum order | 5 racks |
| Lead time | 25 to 30 days from deposit |
| Packing | Rack frame and modules crated separately, assembled on site |
| HS code | 8507.60 |
| Terms | FOB Ningbo, CIF, or EXW |
| Drawings | Supplied on request, model by model |
We cannot quote freight until the rack envelope is confirmed. The datasheet has no dimensions and no weight, and a rack ships by volume rather than by mass, so the crate size decides the price. Ask for the drawing first and the freight follows the same day.
Modules and frame travel separately. That is normal for a rack, it keeps each carton inside manual handling limits, and it means the customer assembles on site with the torque figures in the manual rather than lifting a full rack into place.
Say whether the modules are going into our frame or an existing 19-inch cabinet. If it is an existing cabinet, we need its internal depth and rail positions before we confirm the module will fit.
INSTALLATION NOTES
Six things the installer needs to know
- IP20 means a room. Not a container, not a canopy, not a wall in a carport. Humidity is rated 5 to 85 percent, which is narrower than the tower range and rules out a coastal plant room without dehumidification.
- Check the room temperature against 25 °C. The 6,000-cycle figure is measured at 25 ± 2 °C. A plant room that sits at 38 °C in August will not deliver it, and the cooling load is part of the project, not an afterthought.
- 748.8 V DC on the big rack. Use a DC isolator and a meter rated above it, and break the string down before touching a module. The string is 208 cells in series; there is no low-voltage part of it.
- Address every module before energising. One master, the rest as slaves on the internal bus, then CAN to the PCS. Two masters on one string is the fault we see most often and it looks like a dead rack.
- Do not mix 100 Ah and 314 Ah modules in one string. Different module energy, different BMS, different current limit. Two separate racks on separate PCS inputs is the correct way to combine them.
- Leave front and rear clearance for airflow. The rack is front-to-back cooled and a closed cupboard door with 50 mm behind it will derate the whole string within an hour. Confirm the door swing and the service access before the frame is bolted down.
Rear of the rack: busbars, per-module breakers and the BMS harness. This is the part that has to be right before the first charge.
QUESTIONS
Six things buyers ask about these racks
Is the 209 kW output real?
No. 200 A at 665.6 V is 133 kW. The 209 kW in the catalogue is the energy figure repeated in the power row, and it only becomes true if the BMS were to pass 314 A, which it is not rated to do. Size the PCS against 133 kW. For a two-hour duty that is fine; for one hour at full power it is not.
What are the dimensions and the weight?
Not printed in our catalogue for either rack page. We supply a drawing per model on request, with the module size, the frame size and the weight of both. Ask before you design a room or book freight, because neither can be done from the electrical table alone.
Can I use a normal three-phase hybrid inverter?
On the four 100 Ah racks, usually yes, provided the battery input reaches the charge voltage, which runs from 345.6 to 518.4 V. On the 665.6 V rack, no: 748.8 V at full charge belongs on a PCS with a 750 or 800 V DC bus. The “compatible with residential inverters” line in our catalogue was written for the home product and does not apply to the top model.
Does it include a PCS, fire suppression or an enclosure?
No, and none of the three is optional in a real project. The rack is modules, a frame, a BMS and a breaker set. The PCS, the fire detection, the room and the commissioning are yours or quoted separately. Ask for a split bill of materials so the gap is visible before the purchase order rather than after.
Can it go outdoors or in a container?
No. IP20, 5 to 85 percent humidity, and a working range of −10 to 50 °C measured at the rack, not at the sky. If the site has no room, the container product is the one to quote, because it brings its own enclosure, cooling and protection.
What does the 6,000-cycle figure assume?
0.2C charge and discharge, 25 ± 2 °C, and end of life at 70 percent of original capacity. That is 20 A on a 100 Ah module. A daily peak-shaving duty at 1C is a harder life than the test, and a plant room at 38 °C is a harder life than 25 °C. Neither invalidates the number, but both mean your site will not match it exactly.
QUICK QUOTE
Send the PCS model and the room
The two numbers that decide the build are the converter’s DC voltage window and your peak kW. Send those, plus the daily kWh and whether the modules go into our frame or an existing 19-inch cabinet, and we come back with the model, the PCS sizing and a price, usually within 12 hours on a working day.
