What to decide before asking for price.

Home Battery Sizing Checklist

• Collect the buyer's average daily load in kWh and target backup duration before shortlisting; 10kWh with 8-hour backup needs a different solution than 10kWh with 2-hour backup.
• Account for depth-of-discharge headroom: usable energy is always less than nameplate, so size nameplate up to leave an operational reserve.
• Check that the buyer's peak load is within the inverter's continuous output rating; a battery with enough energy but an inverter too small will trip on startup.
