Sunsynk 5.12kWh Battery

The Sunsynk 5.12kWh Battery (SUNSYNK-L5.1) 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:

• 4.61 kWh Usable - Rated at 5.12 kWh, of which 4.61 kWh is usable - a depth of discharge of 90%. Usable capacity is the figure to size against - it is what you actually get out of it between sunset and sunrise.
• 100 A Charge - Charges and discharges at up to 100 A, peaking at 150 A for a motor starting.
• 51.2 V Nominal - Operates between 43.2 and 57.6 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.
• Talks to the Inverter - CAN2.0, RS485. 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 32 in Parallel - Start with one and add more as the load grows, up to 32 together, without replacing what is already installed.
• The Unit Itself - Rated IP65, 100 Ah, 50 kg. Worth checking against where it is going to live and what is going to carry it.
