Greenrich Lithium Battery Wall Mount 4.95kWh WM5000
Description
4.95kWh of storage. 7.5kW of continuous output.
Most 5kWh-class lithium batteries are rated at 1C continuous discharge, meaning a 5kWh battery can deliver around 5kW of continuous power — fine for steady residential loads, but it can start to throttle when something demanding kicks in. The Greenrich WM5000 is rated at 1.5C continuous, which changes the maths: the same 4.95kWh storage capacity delivers up to 7.5kW of continuous output power from a single unit. For real-world South African homes and small businesses, that's the difference between a battery that covers your essential loads and a battery that handles the bigger ones too.
Under the hood it's a 51.2V (16-cell) LiFePO4 lithium iron phosphate battery — the chemistry chosen for its thermal stability and long cycle life. 96.6Ah of capacity sits behind an integrated Battery Management System that handles cell balancing, current limiting, and a comprehensive set of protections: under-voltage, short circuit, low/high temperature on both charge and discharge, over-current on both charge and discharge, and a dormancy function for storage periods. Communication runs over CAN, RS485 and RS232, with documented compatibility for Deye, Sunsynk, Growatt and Luxpower inverters (per manufacturer documentation — confirm specific firmware compatibility with your installer).
The unit is wall-mounted by design — ~48kg in a footprint that's roughly 586 x 366 x 175mm — which keeps floor space free and makes it suitable for installations where a server rack isn't practical. Greenrich rates the battery for 6000 cycles and offers a 10-year warranty (per manufacturer documentation; confirm registration requirements with your supplier).
What this battery can actually run:
- Geyser cycles — element-driven loads that lower-rated batteries can struggle with
- Air conditioner start-up surges — particularly inverter-driven units kicking into cooling mode
- Borehole and pool pumps — motor inrush currents that often trigger throttling on 1C batteries
- Multiple high-draw appliances simultaneously — kettle + microwave + dishwasher overlap during peak meal times
- Small workshop tools — drill presses, compressors, welders within rated capacity
The point isn't that the WM5000 stores more energy than other 5kWh batteries — it doesn't. The point is that when the energy needs to come out fast, this unit handles it.
