A 10 kWh daily load doesn\u2019t mean a 10 kWh battery bank.<\/p>\n\n\n\n
Once you factor in inverter losses, two days of cloudy weather, and an 80% discharge limit for LiFePO4, that same 10 kWh load actually needs a 25 to 30 kWh bank<\/strong> to keep your inverter from cutting out.<\/p>\n\n\n\n Use the calculator below to turn your daily consumption and system voltage into the exact Ah, kWh, and series-parallel pack layout you need. If you’re planning the complete installation, explore our engineering breakdown of off-grid solar system components<\/a> or consult our LiFePO4 voltage chart<\/a> for resting state-of-charge thresholds.<\/p>\n\n\n\n Adjust daily energy demand, autonomy requirements, system voltage, and battery chemistry below to generate your nominal bank rating and modular string layout. Enter an optional peak load to run a continuous discharge current check.<\/p>\n\n\n\n Daily load, autonomy, voltage, and chemistry in.
