What inverter works with the WT5100?

It is built for 48V-class hybrid and off-grid inverters that support 51.2V LiFePO4 banks. Check that your inverter's communication protocol is supported before wiring closed-loop communications; otherwise run it in voltage mode.

How many units can I run together?

Up to 63 units can be paralleled, giving a very large bank. In practice, keep cable lengths equal and match firmware across units.

Does it include a rack cabinet or cables?

No. It is the battery module only. You supply the 19-inch rack cabinet, DC cables, breaker and inverter.

How long will it last?

The rated cycle life is up to 6,000 cycles, and the warranty runs 10 years. Real life depends on depth of discharge and temperature.

Can it be charged below freezing?

LiFePO4 cells should not be charged below 0°C. There is no built-in heater, so plan for a heated space or a charge cutoff in cold installations.

Our take on the Wirentech 48V (51.2V) 100Ah Server Rack Lithium Battery

The Wirentech WT5100 is a 51.2V 100Ah LiFePO4 server rack battery rated at 5.12 kWh. It stacks into 19-inch rack cabinets and can run in parallel with up to 63 units, so one model scales from a small backup bank to a large whole-home bank. It carries UL 1973 and UL 9540A listings, a 10-year warranty and a 6,000-cycle rating, which puts it alongside other rack batteries from EG4, Pytes and SOK. At 99 lbs it is heavy for one person to lift into a rack, and it is a bare battery: the inverter, cabinet and communications setup are separate purchases.
