We had a client who needed storage for a small commercail solar setup, about 30 panels on a warehouse roof, and the AC output had to handle a 6KW continuous draw from industrial fans and some lighting, so this CPALL6K unit with the 11KW inverter option actually fit the brief better than anything else we'd looked at, and the Bluetooth monitoring meant we could check the state of charge remotely without a full SCADA system.
It's basically a 51.2V DC nominal stack with LiFePO4 cells from EVE or CATL (we usually get BYD depending on stock), and the cycle life is rated at 6000+ cycles at 100% DOD, which for a daily cycling scenario gives you roughly 16 years of use before you hit the 80% capacty mark — and the warranty is 5 years standard but you can extend it to 10 (check lead time on that, it's not always in stock). The dimnesions are 483 by 393 by 871mm and it's floor mounted with rollers, so moving a 200kg unit into position is actually manageable with two people and a dolly.
For the communication side, it talks RS485 and CAN natively, which is pretty much plug-and-play with Growatt and Deye inverters, but we found the Bluetooth app isn't great for real-time data logging — it's fine for a quick check but don't rely on it for granular trend analysis. Parallel connection goes up to 6 units for a max of 240KWh, so you could scale it for a larger commercial install, but weight gets up to 300kg or so for the 400AH version, and that's a limitation for tight spaces or upper floors without a freight elevator.
Also, it's not suited for off-grid cabins with no inverter compatibility — you'll need to verify your inverter's CAN protocol first, as some cheaper brands don't play nice with the BMS, and we've had a few returns from buyers who skipped that step.
Temperature range is -20°C to 55°C, which is better than most LFP packs we've handled, and the efficieny is listed at ≥95%, though in practice we see about 92-93% at full load. We ordered 4 units for this project at 200AH each, with the 5-year warranty, and the supplier confirmed stock within 20 days or so.
We can start with a single unit for small projects, but typical MOQ is 10 units for custom configurations. Let us know your volume, and we’ll work with you on pricing.
Standard lead time is 15-20 working days after order confirmation. Custom builds with higher capacities might add a few days, but we’ll keep you updated.
Yes, CE, UN38.3, and MSDS documents are included with every shipment. We can also provide them in advance if your customs or installer needs a copy.
Absolutely, up to 6 units can be paralleled for a max of 240KWh. They work with Growatt, Deye, Goodwe, Victron, and most major inverters—just confirm your model so we can pre-set the communication protocol.
Keep it in a cool, dry place between -20°C and 55°C, ideally around 50% charge. If you’re storing for over 3 months, check the Bluetooth app monthly to maintain charge level.
