WHO THIS IS FOR
One column instead of a battery, a wall inverter and a conduit run
This family exists for the job where the inverter and the battery have to arrive together. One crate, one set of terminals, one commissioning sheet. The MPPT is already inside, so the panels land on the unit directly and there is no separate solar charger on the wall.
It suits a house that is still being wired, a container office on a site with no grid, a telecom hut where nobody wants to mount three boxes and label four breakers. It does not suit a house that already has a hybrid inverter on the wall and only needs capacity: for that, buy the low-voltage stacked battery and leave the inverter where it is.
It also does not suit anything three-phase, or any project above 16.07 kWh in a single enclosure.
The 16.07 kWh build: 1,150 mm tall, 440 mm wide, 242 mm deep. Inverter sits above the battery in the same column.
FOUR BUILDS, TWO PLATFORMS
Same name on the catalogue page, different hardware underneath
The catalogue puts four models under one heading. They are built on two platforms that share very little: different battery current, different PV capacity, different enclosure rating, and only one of them parallels. Read the platform row before you read the capacity.
| Model | Inverter | Battery | Max PV array | Parallel | Weight | H × W × D |
|---|---|---|---|---|---|---|
| PLATFORM A · 51.2V · 200A · IP21 · PARALLEL TO 5 | ||||||
| 6 kW / 10.24 kWh | 6 kW | 51.2V 200Ah | 9,000 W · 120A | Up to 5 | 85 kg | 1150 × 440 × 242 |
| 6 kW / 16.07 kWh | 6 kW | 51.2V 314Ah | 9,000 W · 120A | Up to 5 | 125 kg | 1150 × 440 × 242 |
| PLATFORM B · 206Ah · 100A · IP20 · NO PARALLEL | ||||||
| 3.6 kW / 5.28 kWh | 3.6 kW | 25.6V 206Ah | 5,000 W · 100A | None | 64 kg | 935 × 444 × 247 |
| 6 kW / 10.54 kWh | 6 kW | 51.2V 206Ah | 5,000 W · 100A | None | 85 kg | 935 × 444 × 247 |
Both 10.24 kWh and 10.54 kWh models weigh 85 kg and look similar on a quote. They are not interchangeable: one parallels to 51.2 kWh of system capacity and takes a 9 kW array, the other stops at itself and takes 5 kW. The 25.6V model runs a 1P8S pack and needs a different setting on the same firmware. Dimensions are the enclosure only, before any wall clearance.
WHAT THE BUILT-IN INVERTER CAN AND CANNOT DO
The inverter is inside, so the compatibility question changes
On a split system you match a battery to somebody else’s inverter. Here the pair is fixed at the factory, and what you have to check is the site: grid form, array voltage at the coldest morning, and what actually starts up on the load side.
| Item | What it does | What you have to check |
|---|---|---|
| Grid form | Single-phase 230V, L + N + PE, 50 or 60 Hz auto | No three-phase output. On a 3-phase supply you either take one phase or you buy a split system |
| PV array | 9,000 W on the 51.2V platform, 5,000 W on the 206Ah platform | String Voc at the coldest morning, not at STC. 500V open-circuit ceiling; 450V upper MPPT window |
| Generator | Accepted on both platforms, with a 20 ms transfer instead of 10 ms | Generator size against the 120A or 100A charge limit, or it will run at part load and wet-stack |
| Parallel | Up to 5 units on the 51.2V platform, none on 206Ah | Parallel adds inverter capacity as well as battery. Load balancing is by the units themselves, not by an external controller |
| Surge | 12 kVA on the 6 kW models, 7.2 kVA on the 3.6 kW | One 1.5 HP compressor starting is fine. Two starting on the same minute is not |
| Efficiency | 93% at 48VDC on the 51.2V platform, 92.7% at 24VDC on the 25.6V model | Quoted battery mode only. Round-trip through the MPPT is lower and depends on array voltage |
SINGLE UNIT OR PARALLEL BANK
When one column is enough, and when it is not
Three 16.07 kWh units paralleled: 48.21 kWh and 18 kW of inverter on one AC bus.
Paralleling is not a way to add battery to an existing unit. Each unit brings its own inverter, its own MPPT and its own battery, and the five of them share the load through the AC side. That is why a three-unit bank gives 18 kW of output, not 6 kW.
It is also why the 206Ah platform cannot do it: those models have no parallel port, and no firmware path to one. If you might grow past 16 kWh, buy on the 51.2V platform from the start.
The practical ceiling: five units of 16.07 kWh is 80.35 kWh and 30 kW. Above that, the cabinet range takes over, and it costs less per kWh than six all-in-one units would.
CERTIFICATION
What the paperwork covers
UN 38.3
Transport test summary for the cell and the module. Freight forwarders will ask for this before they accept the shipment.
CE & RoHS
Issued per model. On this family the inverter also needs its own EMC and safety file, not only the battery. Ask for both report numbers.
ISO 9001
Plant level, covering the Hangzhou site. Relevant for EPC prequalification rather than for the product itself.
TYPICAL CONFIGURATIONS
Three builds we ship most often
Examples, not guarantees. Sizing still depends on the load profile and how much sun the site gets.
A 16.07 kWh column on a garage floor, panels on the roof above. No wall inverter, no separate solar charger.
HOUSE, ROOF-TIED
6 kW / 16.07 kWh
Plus 8 kW of panels into the built-in MPPT. Runs a fridge, lighting, a router and one 1.5 HP air conditioner through a 12-hour night with roughly a third left. A second air conditioner is where this model stops and a parallel unit starts.
125 kg · 1150 × 440 × 242
SHOP, DAYTIME LOAD
6 kW / 10.24 kWh
A small workshop drawing 2 kW of lights, tools and a fridge for four hours after closing. That is 8 of the 9.2 kWh usable, so there is little margin in a cold week. Most shops on this build parallel a second unit within a year.
85 kg · 1150 × 440 × 242
CABIN OR HUT, NO GRID
3.6 kW / 5.28 kWh
Two 550 W panels and a 700 W site load: lights, a laptop, a small pump. About 6 hours on battery, generator takes over through the GEN input when the weather holds for three days.
64 kg · 935 × 444 × 247
BUYING INFORMATION
What the order actually looks like
| Minimum order | 30 units per model. Mixed builds in one container are possible once the total reaches a full load. |
| Lead time | 20 to 25 days after the deposit clears, counted from payment. Longer than the battery-only families because the unit is commissioned and load-tested before packing. |
| Packaging | One unit per carton on a pallet, foam at all four corners, base strapped. The 125 kg build ships upright and must stay upright: mark the carton and tell the forwarder, because a unit laid on its side has to be re-inspected before it is energised. |
| Gross weight | Add about 10 percent to the net weight. The all-in-one carton is larger than a bare module of the same energy. |
| HS code | 8504.40 for the inverter side, 8507.60 for the battery. An all-in-one unit is classified on the function that gives it its essential character, so confirm with your broker before the first shipment. Do not assume one code for the whole family. |
| Trade terms | FOB Ningbo or CIF to your port. EXW is available if you have your own forwarder. |
INSTALLATION NOTES
Six things the installer needs to know
- Two people above 100 kg. The 16.07 kWh unit is 125 kg in a 440 mm wide column with no lifting eyes. Two people and a stair-climbing trolley, or a crane for a first floor.
- Point load on a timber floor. 125 kg stands on 0.11 m², which is about 1.2 t/m² under the feet. On a wooden first floor, use a spreader plate; on concrete, nothing needed.
- IP21 means fingers and dripping water. The second digit is about water, not dust: there is no dust rating at all at this level, and no protection against spray. A garage floor is fine; a carport in a wet season is not. The 206Ah platform is IP20, which drops the water protection entirely.
- Clearance for the fan. Natural cooling, so the unit needs 100 mm at the sides and 200 mm above to convect. A unit boxed into a cupboard will derate in August, not fail, which is worse because nobody notices.
- Charge below zero is blocked. Charging window starts at 0 °C. An unheated site in a cold season will sit idle in the morning; either heat the room or accept the lost hours.
- One breaker, one label. The unit has an AC input, an AC output and the PV input on the same enclosure. Label all three at the consumer unit. The next electrician will not read the manual.
Front face: LCD, four LEDs for AC, inverter, charge and fault, and the DC breaker under a clear cover.
QUESTIONS
Six things buyers ask about this family
Can I add a second unit later to get more capacity?
Only on the 51.2V platform, and only up to five units. On the 206Ah platform there is no parallel port and no firmware path to one, so the capacity you buy is the capacity you keep. This is the decision to get right at the quotation stage, because it cannot be fixed in the field.
Can it supply a three-phase load?
No. The output is single-phase 230V. On a three-phase supply you can feed one phase from the unit and leave the other two on the grid, which covers lighting and socket circuits but not a three-phase motor or a three-phase chiller. For those, use the C&I cabinet range with its own PCS.
What happens if the inverter fails?
The battery cannot be separated from it in the field. The whole unit goes back for repair, which on a 125 kg build means a crate leaving your site and a replacement arriving before the customer has power again. We would rather say this now than after the first failure. It is the main reason installers still choose split systems on high-value projects.
How much panel can I connect, and what if I oversize?
9,000 W on the 51.2V platform and 5,000 W on the 206Ah platform, with the charger clipping at 120A or 100A. Oversizing the array is normal and safe up to the 500V open-circuit ceiling; the excess is clipped rather than stored. What is not safe is passing 500V on a cold morning, so check string Voc at the lowest site temperature before you order panels.
Will it start an air conditioner or a well pump?
One 1.5 HP compressor starts comfortably on the 6 kW models with 12 kVA of surge. A deep-well pump is harder, because its starting current lasts longer than a compressor’s. Send us the pump nameplate: locked-rotor current, not running watts. Two motors starting in the same minute is where these units trip, and no surge figure on a datasheet tells you that.
What is the warranty, and what voids it?
The catalogue prints one year, covering manufacturing defects. The 6,000-cycle rating at 90% depth of discharge and the 8 to 10 year design life are separate from that and are not a warranty term. If your tender needs a longer period, raise it before we quote rather than after the contract is signed. Warranty is voided by charging below 0 °C, by parallel connection on a model without a parallel port, and by opening the enclosure.
