Lithium Solar Batteries

1. Calculate Your Energy Needs: Determine your daily power consumption, considering all appliances and devices you’ll use. This will help you size your battery, solar panels, and other components.
2. Mount the Battery: Secure the battery enclosure near your inverter, ensuring adequate ventilation.
3. Connect DC Cables: Run appropriately sized positive and negative cables from the battery’s BMS terminals to the inverter’s battery input.
4. Link to Solar Charge Controller: If using a dedicated MPPT, wire its battery output to the same DC bus.
5. Integrate Monitoring: Connect the BMS communication port (RS485/CAN) to your inverter or gateway for real-time data.
6. Verify & Energize: Tighten all terminals, confirm polarity, then switch on the battery and inverter in sequence per WattCycle instructions.

At WattCycle, we build our lithium batteries using highest quality materials for long-lasting performance. Designed to get the most out of your solar setup, they’re ready for both on-grid and off-grid use. And with zero maintenance required, you can count on steady power—no check, no fuss, just energy independence on your terms.

Array Sizing: Aim for a PV array capacity 1.2–1.5× your lithium battery bank’s watt-hour rating to replenish daily depth of discharge.

Charge Controller Settings: Set bulk/absorption voltage to 14.4 V (for 12 V systems) and float to 13.6 V; enable temperature compensation if available.

Seasonal Adjustments: In low-sun months, reduce discharge depth to 40 %–50 % and consider shifting absorption time longer; in high-sun seasons, you can safely utilize up to 80 % DOD for maximum yield.
