WHO THIS IS FOR
A battery bank you size in the field, not in the quotation
This family replaces a fixed-capacity wall battery. You mount the base plate once, land four cables, and from then on capacity is a hardware decision rather than a new order. One module today, three next year, five when the customer finally buys the air conditioner they were talking about.
It suits installers working with 48V hybrid inverters who need a documented CAN map and a stack that does not need a master controller between modules. It does not suit outdoor sites, because the enclosure is IP20. For those, look at the high-voltage stacked tower.
One 314Ah module, 16.08 kWh. The stack starts here and grows upward.
TEN BUILDS
Two module sizes, five heights each
The 100Ah body is 143 mm tall per module and stops at 25.6 kWh. The 314Ah body is 230 mm tall and reaches 80.4 kWh. You cannot mix the two on one stack, so pick the body before you pick the height.

Stack height is the modules only and does not include the base plate, which adds about 60 mm. Width is 440 mm and depth 586 mm on the 100Ah body, 742 mm on the 314Ah body. Energy figures are nominal at the module level; usable energy at 90% DoD is about ten percent lower.
Same width and height, different depth
Both bodies are 440 mm wide and 51.2V. The difference is how far they reach back: 586 mm on the 100Ah body, 742 mm on the 314Ah one. That 156 mm decides whether the stack fits the alcove you have in mind.
The 314Ah body also carries 2.3 times the energy per layer, which is why a five-module tower reaches 80.4 kWh at 1,150 mm of modules instead of needing eight layers of the smaller body.
INVERTER COMPATIBILITY
48V hybrid inverters, single or three phase
The stack talks CAN and RS485. It has no inverter of its own, so the profile has to match whatever you already installed. We publish the register map, which means your own controller can read it without a gateway.
| Protocol | What it carries | What you have to confirm |
|---|---|---|
| CAN | Cell voltage, temperature, SOC, charge and discharge limits | The inverter accepts a 48V-class CAN profile, not a high-voltage one |
| RS485 | The same data plus firmware version and alarms | Baud rate and register map version. Send us the inverter model and we return the matching profile |
| Dry contact | Alarm output only | Not a substitute for CAN if you want SOC control |
CERTIFICATION
What the paperwork covers
UN 38.3
Transport test summary for the cell and the module. This is what freight forwarders ask for before they accept a lithium shipment.
CE & RoHS
Issued per model, not per family. Ask for the report number that covers the exact build you are buying, because a certificate for the 100Ah body does not cover the 314Ah one.
ISO 9001
Plant level, covering the Hangzhou site. Useful for EPC prequalification rather than for the product itself.
TYPICAL CONFIGURATIONS
Three builds we ship most often
These are examples, not guarantees. Sizing still depends on your load profile and how much sun the site gets.
Three modules, a wall-mounted inverter and four metres of conduit. A utility room, not a plant room.
HOUSE, NIGHT BACKUP
3 × 314Ah · 48.24 kWh
Paired with an 8 kW hybrid inverter. Runs a fridge, lighting, a router and one 1.5 HP air conditioner through a 12-hour night, and still has about 60 percent left.
Weight 318 kg · height 690 mm
SMALL SHOP, SELF USE
5 × 314Ah · 80.40 kWh
Paired with a 10 kW three-phase inverter. Carries a 6 kW daytime load for about 10 hours, or absorbs the roof output between 9 am and 3 pm and releases it after closing.
Weight 530 kg · height 1,150 mm
REMOTE HUT, NO SUN
2 × 100Ah · 10.24 kWh
Paired with a 3 kW off-grid inverter. A monitoring hut drawing 350 W continuously runs about 26 hours without sun, enough for a site on a weekly maintenance round.
Weight 92 kg · height 286 mm

INSTALLATION NOTES
Six things the installer needs to know
- Indoor only. IP20. A garage is fine, a covered outdoor wall is not.
- Base plate first. Level the plate before the first module goes on. A stack built on an uneven floor leans more with every layer.
- Anti-tip strap above three modules. The stack stands on its own plate, but a 318 kg tower next to a walkway needs a strap for anything above three modules.
- Equal-length parallel cables. When you parallel two stacks, keep the positive and negative runs the same length, or the nearer stack carries more current and ages faster.
- Do not parallel different batches. A new stack next to one that has been cycling for a year will fight it over current sharing. Add capacity with a stack of similar age, or accept the mismatch and derate.
- Altitude derating. Rated to 4,000 m, but above 2,000 m the continuous current has to come down. Tell us the site altitude at enquiry if you are above 1,500 m.
Rear face: busbar lugs, breaker, CAN and RS485 ports. Four cables land here and nothing else.
QUESTIONS
Six things buyers ask about this family
Can I mix 100Ah and 314Ah modules on the same stack?
No. Each module body has its own BMS profile, and a stack is built to one profile. If you start on the 100Ah body you top out at 25.6 kWh with five modules. Moving to 314Ah later means a second stack, not an extra module. This is the choice you cannot undo, so pick the body size at the start.
How tall is a five-module stack, and will it fit under a shelf?
The 314Ah body at five modules is 1,150 mm of modules plus about 60 mm of base plate, so roughly 1,210 mm. The 100Ah body at five modules is 715 mm plus the plate. Width is 440 mm on both. Measure the ceiling and any shelf above before the base plate goes down, because the stack cannot be laid on its side.
Can it be installed outdoors?
No. The enclosure is IP20, which means it is protected against fingers and dust ingress in a room, not against rain. For an outdoor site, the high-voltage stacked tower is IP55 and built for it, or you put this family in a cabinet with its own weather protection and ventilation.
What inverter does it work with?
Any 48V-class hybrid inverter with a CAN or RS485 battery input. The stack does not include an inverter and does not include an MPPT, so the solar side belongs to your inverter. Send us the model before ordering and we will confirm the profile in writing rather than letting you find out at commissioning.
How do I parallel two stacks?
Run the DC cables from each stack to a common busbar, keep the runs equal in length, and set one stack as the master. Up to ten modules can be paralleled in total on the low-voltage platform, but the inverter’s maximum battery current usually caps you before that. Check the inverter limit first.
What is the warranty, and what voids it?
Ten-year design life and a 6,000-cycle rating at 90% depth of discharge and 25 degrees. The warranty is voided by operation outside the temperature window, by paralleling different batches without telling us, and by opening the module enclosure. We do not refuse warranty claims for normal capacity fade, only for those three.
QUICK QUOTE
