Solar Power Inverter FAQ

  1. What is MPPT in solar inverter?

    An MPPT, or maximum power point tracker is an electronic DC to DC converter that optimizes the match between the solar array (PV panels), and the battery bank or utility grid.

  2. Can I use MPPT without inverter?

    It is possible but will not always be stable, it also depends on the loads you are running. Most inverters and mppts use the batteries as a reference for production and voltage stability.

  3. Does solar inverter need battery?

    Off-grid systems require an extra charge controller component to send the solar power to a battery bank before the inverter converts the DC to AC. Standalone solar inverters always need a battery bank to function.
