WHO THIS IS FOR
Three-phase output from a 48 V battery
Most 48 V systems are single-phase, because 48 V and three phases is an awkward pair: a 12 kW three-phase load pulls 234 A out of the battery. This cabinet is built for exactly that job. It takes a three-phase supply, adds up to 19.2 kW of PV through two trackers, and stores 16 to 80 kWh at 51.2 V.
It suits a workshop or small factory on a three-phase supply that wants to shave its peak and ride through a short outage, a cold store or a pump station where the load is 5 to 10 kW and the grid is unreliable, and any site that has a three-phase board and no room for a separate inverter and battery room.
It is not the cheap way to 80 kWh. The 261 kWh cabinet carries three times the energy in a bigger footprint at a lower cost per kWh, and the rack family carries the same energy without an inverter for a customer who already owns a PCS. This cabinet is for the case where one box on a wall replaces three boxes on a floor.
661 mm wide, 1,432 mm tall on the five-module build. One door, one cable entry, one breaker.
THE SEVEN MODELS
The same 16.07 kWh module, one to five times
Every model uses the 51.2 V 314 Ah module, 16.07 kWh, in parallel. Capacity is the module count times 16.07. The inverter comes in 8, 10 and 12 kW, and that is the choice that matters, because the battery can only feed so much.
| Model | Modules | Capacity | AC power | AC current | Max PV | Cabinet size |
|---|---|---|---|---|---|---|
| 8kW / 16kWh | 1 | 16.07 kWh | 8 kW | 11.6 A | 12,800 W | 661 × 938 × 947 |
| 8kW / 32kWh | 2 | 32.15 kWh | 8 kW | 11.6 A | 12,800 W | 661 × 947 × 1432 |
| 10kW / 16kWh | 1 | 16.07 kWh | 10 kW | 14.5 A | 16,000 W | 661 × 938 × 947 |
| 10kW / 48kWh | 3 | 48.23 kWh | 10 kW | 14.5 A | 16,000 W | 661 × 947 × 1432 |
| 10kW / 64kWh | 4 | 64.30 kWh | 10 kW | 14.5 A | 16,000 W | 661 × 947 × 1432 |
| 12kW / 16kWh | 1 | 16.07 kWh | 12 kW | 17.4 A | 19,200 W | 661 × 938 × 947 |
| 12kW / 80kWh | 5 | 80.38 kWh | 12 kW | 17.4 A | 19,200 W | 661 × 947 × 1432 |
All seven share the same battery: 51.2 V, 314 Ah, charge cut-off 57.5 V, discharge cut-off 44.8 V, 200 A maximum, IP55, 6,000 cycles. AC output at 220/380 or 230/400 V, 50 or 60 Hz, THD within the 0.85–1.1 Un window, off-grid transfer under 6 ms, peak power twice rated for 10 s, 97.6 percent maximum efficiency.
Door open: battery modules in the upper section, inverter and AC terminals below, DC breakers between them.
THE ONE BUILD TO WATCH
A 12 kW inverter on a one-module cabinet
One 314 Ah module passes 200 A. At 51.2 V that is 10.24 kW, whatever the inverter label says. Six of the seven models have enough modules to cover their inverter; one does not.
| Model | Modules | Battery can give | Inverter asks at full power | Verdict | What it means on site |
|---|---|---|---|---|---|
| 8kW / 16kWh | 1 | 10.24 kW | 156 A | Fine, 78 percent used | Headroom for surge |
| 10kW / 16kWh | 1 | 10.24 kW | 195 A | Just fits, 98 percent | No margin on a hot day |
| 12kW / 16kWh | 1 | 10.24 kW | 234 A | Capped at 85 percent | Cannot reach 12 kW |
| 8kW / 32kWh | 2 | 20.48 kW | 156 A | Fine | Two modules share the current |
| 10kW / 48kWh | 3 | 30.72 kW | 195 A | Fine | Comfortable |
| 10kW / 64kWh | 4 | 40.96 kW | 195 A | Fine | Comfortable |
| 12kW / 80kWh | 5 | 51.20 kW | 234 A | Fine | Five modules in parallel |
WHY IT MATTERS
The 12 kW single-module build is the cheapest way into three-phase 12 kW in our range, so it is the one a distributor will price first. The customer gets 10.24 kW and an inverter that folds back to protect the battery, on the afternoon they need it most.
THE 10 kW ONE IS BARELY BETTER
195 A against a 200 A limit is 2.4 percent of margin. Ambient at 45 °C, a cell imbalance, or an aging pack and it derates. It works, but it works with nothing in reserve.
WHAT TO SELL INSTEAD
If the load really is 12 kW, quote the 12kW / 80kWh or step down to 10 kW. There is no 12 kW two-module model in the range, which is the gap worth closing in the next revision.
THE PV SIDE
19.2 kW of panels, 10.24 kW of charging
Two MPPT trackers, 800 V maximum input, 160 V start-up, and up to 19,200 W of array. The number that decides the design is not the array size but the charge current, because 19.2 kW divided by 51.2 V is 375 A and the battery accepts 200.
| Parameter | 8 kW models | 10 kW models | 12 kW models |
|---|---|---|---|
| Maximum PV power | 12,800 W | 16,000 W | 19,200 W |
| Maximum input current | 17 + 17 A | 30 + 30 A | 30 + 30 A |
| MPPT trackers | 2 | 2 | 2 |
| Maximum PV voltage | 800 V | 800 V | 800 V |
| Start-up voltage | 160 V | 160 V | 160 V |
| MPPT voltage range | Printed as 0. Ask us for the real window | ||
WHY THE ARRAY IS BIGGER THAN THE CHARGER
On a sunny day the array feeds the load first and only the surplus goes to the battery, so 19.2 kW of panels on a 12 kW inverter is not wasted: it means the cabinet runs at full output without touching the battery. What it will not do is charge at 19.2 kW, because 200 A caps charging at 10.24 kW.
THE MISSING ROW IS THE IMPORTANT ONE
Without the MPPT window nobody can design a string: 800 V is the ceiling and 160 V is where it wakes up, but the tracking floor decides how many panels you can put in series on a short winter day. Do not size a roof off the 800 V figure alone.
Two strings, one tracker each, DC isolator at the cabinet. 30 + 30 A is the input limit, not the array size.
PROTECTION AND CONDITIONS
Three ratings, three different numbers
BATTERY IP55
Dust protected and splash resistant from any direction. Adequate for a wall under a roof overhang, not for a wash-down bay or standing water.
INVERTER IP65
Jet resistant. The cabinet is only as protected as its weakest section, so read the whole unit as IP55 for outdoor siting.
TEMPERATURE, THREE RANGES
Inverter −25 to 60 °C, battery discharge −10 to 55 °C, battery charge 0 to 55 °C. The cabinet runs below freezing and refuses to charge below zero.
| Cycle life | 6,000 cycles, about 10 years |
| Warranty | 5 years, printed on the datasheet |
| Cooling | Air cooled, natural on the battery |
| Noise | ≤55 dB at one metre |
| Communication | 2 × CAN |
| Operating mode | Grid-tied with backup, transfer under 6 ms |
The five-year warranty is worth putting on the page. Most of our range prints a design life and no warranty term; this cabinet prints 5 years. A distributor comparing three Chinese suppliers will notice, and it is the only document-backed promise in the range.
55 dB is louder than people expect from a battery. It is the inverter fan, not the battery. Do not site the cabinet against a bedroom wall or a shared boundary where the neighbour sleeps.
The 6,000-cycle figure still has no depth of discharge attached. Everything on this page assumes 90 percent, which is the number our other low-voltage families print.
TYPICAL CONFIGURATIONS
Three builds that work, one that does not
All four are calculated at 90 percent depth of discharge and checked against the 200 A battery limit.
01 · WORKSHOP, THREE-PHASE
80.38 kWh · 12 kW
72.3 kWh usable carries an 8 kW evening load for nine hours, and 12 kW peak is no problem with five modules sharing 234 A. This is the build the 80 kWh keyword actually means.
Cabinet height 1,432 mm, so check the door and the plinth first.
02 · COLD STORE, 8 kW
32.15 kWh · 8 kW
28.9 kWh usable is 5.8 hours at 5 kW of refrigeration load, and 8 kW peak leaves the battery at 78 percent of its limit. Two modules in parallel, so a single module fault does not take the site down.
Charge stops at 0 °C: a plant room below freezing will not recover overnight.
03 · SMALL OFFICE BACKUP
16.07 kWh · 10 kW
14.5 kWh usable runs 2 kW of IT and lighting for seven hours, with 10 kW available for the lift or the air conditioning start. 195 A against 200 A, so it fits with almost no margin.
The right choice when the load is small but the surge is not.
04 · THE ONE WE TALK PEOPLE OUT OF · 12kW / 16kWh
A customer asks for 12 kW and the smallest cabinet, because it is the cheapest way to get a three-phase 12 kW label. The battery gives 10.24 kW, so the inverter never reaches its rating and the customer concludes the product is weak. Quote the 80 kWh build, or quote 10 kW and explain that the load will be covered. Losing a small order here is cheaper than a warranty argument about a machine that never delivered what the nameplate said.
BUYING INFORMATION
What the order actually looks like
| Minimum order | 5 cabinets |
| Lead time | 25 to 30 days from deposit |
| Packing | One cabinet per pallet, crated upright |
| HS code | 8504.40 (inverter) or 8507.60 (battery) |
| Terms | FOB Ningbo, CIF, or EXW |
| Warranty | 5 years, terms available |
HS classification is a real question on this product. It is an inverter and a battery in one box. Most customs authorities classify by the function that gives the unit its essential character, and that judgement varies. Ask your broker for a written ruling rather than accepting ours.
No weight is printed anywhere on this datasheet. A 80.38 kWh cabinet is close to a tonne and the pallet is a crane or forklift job, not a two-person lift. We will supply the weight with the drawing; do not book freight without it.
The battery is inside the cabinet, so the cabinet ships as one unit and cannot be broken down for a narrow stair.
INSTALLATION NOTES
Six things the installer needs to know
- 661 mm wide, and a door that opens further. Allow 600 mm of clear space in front for the door swing and for pulling a module out of the rack inside. A 900 mm corridor is the practical minimum, not 700.
- Two heights, so measure the route. The single-module build is 938 mm and the multi-module build is 1,432 mm. A 1.4 m cabinet does not go through a 1.1 m doorway on its side without a fight, and it should not travel on its side at all.
- Charge stops at 0 °C. The inverter runs to −25 °C and the battery discharges to −10 °C, so the cabinet looks alive in a cold snap and simply will not charge. Say this to the customer before the first winter, not after.
- Neutral and earth are not optional. Three-phase output with backup means the transfer is live; the 6 ms changeover will hold a PC up but will not hold a compressor. Confirm what the customer expects to ride through.
- 55 dB at one metre. Fan noise, continuous. Do not put it on a party wall, and do not promise a silent cabinet.
- Set the export limit before commissioning. With 19.2 kW of PV and a 12 kW inverter the surplus has to go somewhere: battery, load, or grid. If the site has no export agreement, set the limit at commissioning or the meter will run backwards and someone will notice.
On a plinth, cable entry from below, 600 mm clear in front. The plinth keeps the base out of standing water.
QUESTIONS
Six things buyers ask about this cabinet
Can the 12 kW model really deliver 12 kW?
Not with one battery module. A single 314 Ah module passes 200 A, which is 10.24 kW at 51.2 V, so the 12 kW inverter runs at about 85 percent of its rating. The 12 kW model with five modules has no such limit. If the load is genuinely 12 kW, specify the 80 kWh build or step down to 10 kW.
What are the dimensions and the weight?
The datasheet prints two cabinet sizes, 661 × 938 × 947 mm and 661 × 947 × 1,432 mm, without saying which model gets which. The shorter one is almost certainly the three single-module builds and the taller one the four multi-module builds, but confirm it with us before you cut a plinth. Weight is not printed at all; ask for the drawing.
What is the MPPT voltage window?
Our datasheet prints the range as 0, which is a placeholder rather than a value. What is printed: 800 V maximum input, 160 V start-up, two trackers, 17 + 17 A or 30 + 30 A of input current. Without the tracking floor you cannot size a string safely, so ask before you design the roof.
Can it be installed outdoors?
The battery is IP55 and the inverter section IP65, so treat the whole cabinet as IP55 and keep it out of direct wash-down and standing water. A wall under an overhang is fine. A coastal site needs the terminals checked each year, and 5 to 85 percent humidity is not printed for this model, so ask if the site is humid.
Is the five-year warranty real, and what does it cover?
Five years is printed on this datasheet, which is unusual in our range and worth quoting. Ask for the terms in writing: what it covers, whether it is parts or replacement, and what the capacity threshold is at year five. A warranty number without a threshold is a marketing figure.
What is the cycle life based on?
6,000 cycles and about 10 years, with no depth of discharge printed for this model. Our low-voltage families assume 90 percent, and every calculation on this page uses that. If your duty cycle is deeper or the plant room runs hot, ask for the test conditions rather than taking the number at face value.
QUICK QUOTE
Send the peak load and the phase count
Tell us the peak kW, the daily kWh, whether the supply is three-phase and what the roof can take. We come back with the model, the module count and a price, usually within 12 hours on a working day. If your peak is above what the battery can feed, we will say so rather than quote it.
