Honestly, in most cases, the 51.2V nominal voltge and 200Ah capacty stack up to a solid 10.24kWh package that fits nicely into a standard 19-inch rack — we've had customers parallel several of these for off-grid setups (usually 2-4 cabinets) without any communication hiccups.
What you're getting here is a LiFePO4 chemistry at that 200A max discharge current, so it'll handle heavy inverter loads for 20 minutes or so, but don't expect it to run a continuous 10kW air conditioner for hours — the 80% DoD cycle life of roughly 8000 cycles is rated at that depth, and we're seeing real-world numbers closer to 6500 in hot climates. CE and UN38.3 are standard on COA, and the BMS covers overcharge and short circuit with a thermal cut-off we actually had to test when a client's cooling fan failed last summer.
58.4V charge voltage to 40V cut-off might seem wide, but it's better than other rack batteries in this class for avoiding premature shutdowns with fluctuating solar input. That built-in BMS also logs cycle counts and temp data (check the UART port if your inverter supports it).
It's pretty much a plug-and-play unit at about 50kg, so two people can rack-mount it without gear — dimensoins are 530x540x260mm, and we typically stock them in single wooden crates. You'll need to specify if you want the parallel communication cable or the wall-mounted bracket, as those aren't always in the box by default.
Anyway, the MOQ is usually 4 units for direct pricing, and our company can do custom label branding if you need, but the 5-year warranty is standard form the factory and covers cell defects and BMS failure — not shipping damage though.
Our MOQ is 10 units for the standard model. If you need a smaller trial order, just let us know and we can work something out.
Lead time is typically 15-20 working days for orders up to 50 units. Larger orders may take a bit longer, but we'll confirm the exact timeline when you order.
Yes, absolutely. We provide CE, UN38.3, and RoHS compliance certificates with every shipment. You'll get the official copies along with the packing list.
The 40V cut-off is set by the built-in BMS and is fixed to protect the cells. We don't recommend changing it, but if you have a specific requirement, we can discuss custom BMS settings for larger orders.
Store them in a cool, dry place between 0°C and 35°C, ideally at around 50% state of charge. Make sure to recharge every 6 months to keep the cells healthy.
