FAQ
Can this replace a full electrical audit?
Use this for planning and shortlist decisions, then validate with measured appliance duty cycles and local irradiance history.
24V solar setup: how many battery Ah do I need?
For this load profile, estimated LIFEPO4 bank sizing is 139.9 Ah at 24V with 1-day autonomy.
How many watts of solar panels are required for 5 peak sun hours?
The calculator estimates 758 W panel capacity after charge and derate factors.
Why does lower battery voltage usually require higher Ah?
For the same energy demand, lower voltage systems need more current. That translates into larger Ah requirements and often thicker cabling.
