Factory Price 51.2V 200Ah Lifepo4 Rack Battery | 5 Years Warranty Energy Storage System

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.
