Inverter And Charging Inputs Explained

These fields control how GridGap interprets running load, surge demand, recharge time, and the practical relationship between battery voltage and inverter output.

Inverter fields

Inverter system voltage defines the DC system voltage the inverter will work from. Inverter efficiency reflects the energy losses between the battery and useful AC output. Inverter headroom factor adds conservatism above the raw running load.

GridGap also analyzes surge-related behavior from appliance data. That is why inverter recommendations often end up higher than simple running watts alone.

Charging fields

Charger efficiency affects how much real charging power is needed to put energy back into the battery. Grid charge hours defines the available charging window from utility input. In RV and boat contexts, this can often be read as grid / shore power charge hours.

Shorter available charge windows usually require a larger charger recommendation to recover the same energy.

AC and installation fields

When installation planning is enabled, AC-side fields expand the result: AC output cable length, cable material, cable type, voltage drop target, installation environment, AC protection preference, cable slack, safety margin, and future expansion.
