Residential system direction
Use more solar after the sun moves on.
Coordinate PV input, daytime demand, battery charging and evening loads as one transparent energy path.
Build this directionThe project question.
Solar storage begins with the household load profile. Daytime generation should first support current demand, while suitable surplus can charge the battery within the inverter and battery operating limits.
A solar-plus-storage direction that explains when energy is generated, stored and used, and which assumptions require an installer review.
A four-step design sequence.
Each step narrows the next decision and keeps the assumptions visible for installer and technical review.
- 01
Map daytime demand
Identify the loads already active during solar hours and the evening demand that storage may need to shift.
- 02
Review PV strings
Keep array voltage, current, open-circuit voltage and MPPT windows within the exact inverter limits.
- 03
Choose battery reserve
Balance daily cycling with the reserve needed for outages or off-grid operation.
- 04
Set operating priorities
Document whether the project prioritises self-consumption, backup reserve, grid charging or generator support.
