GreenRich 4.95kWh Battery (WM5000)

The GreenRich 4.95kWh Battery (WM5000) is a lithium iron phosphate (LiFePO4) battery for storing the day's solar and carrying a house through the evening and the night. One of these carries the essentials overnight - lights, plugs, the router, the television and a fridge. Add a second when the geyser or the stove has to stay on as well.

Key Features & Specifications:

• 3.96 kWh Usable - Rated at 4.95 kWh, of which 3.96 kWh is usable - a depth of discharge of 80%. Usable capacity is the figure to size against - it is what you actually get out of it between sunset and sunrise.
• 80 A Charge / 150 A Discharge - Takes charge at up to 80 A and gives it back at up to 150 A, peaking at 350 A for a motor starting.
• 51.2 V Nominal - Operates between 44.8 and 57.4 V, which is the window the inverter has to match - a battery and an inverter that do not overlap here will not work together whatever else they have in common.
• 6,000 Cycles - One cycle is one full charge and discharge. At a cycle a day that is roughly 16 years of daily use before the rated capacity falls away.
• Talks to the Inverter - CAN, RS485, RS232. The battery tells the inverter its state of charge and its limits, so charging stops where it should instead of at a guessed voltage.
• Up to 15 in Parallel - Start with one and add more as the load grows, up to 15 together, without replacing what is already installed.
• The Unit Itself - Rated IP20, 96.6 Ah, 48 kg. Worth checking against where it is going to live and what is going to carry it.
