FAQ
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.
Should I oversize panels or batteries first?
In low-sun conditions, panel oversizing usually improves daily recovery. In high-cloud windows, additional battery autonomy reduces outage risk.
Is LIFEPO4 efficient for this load profile?
Yes, the model applies chemistry-specific assumptions for DoD and charging to keep estimates closer to practical planning ranges.
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.
