    Lithium Solar Batteries

    WattCycle’s LiFePO4 deep cycle solar battery stands guard over your home’s power and cuts your electricity bills.

    Step-by-Step Solar System Installation Guide

    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.

      Power Your Green Life with Confidence

      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.

      • On-Grid

      A solar on-grid system, also known as a grid-tied solar system, is linked to both the solar panels and the main grid. This means you can draw power from your panels or the grid, and you can also automatically send excess solar power to the grid.

      • Off-Grid

      An off-grid solar system is a solar panel system that has no connection to the utility grid at all. This means that all of your system's power comes from the panels, so you don't need to rely on an external power source. You can meet your energy needs entirely through solar power and stored batteries.

      • Hybird

      A hybrid solar system is a system that uses the combination and integration of solar power with a backup power source (usually a generator or the main grid) and battery storage to generate electricity.

      Best Advice for Charging LiFePO4 with Solar

      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.
