Hybrid solar
Battery backup meets grid connection
The best of both worlds — generate and store your own solar, stay on during outages, and still benefit from PLN grid credits.
How it works
Solar + battery + grid, intelligently managed
- Solar DC flow
- AC to loads
- PLN backup (one-way)
- Battery discharge
Panels generate DC power
Solar panels on your roof generate direct current (DC) electricity whenever the sun shines.
Inverter converts & manages
The hybrid inverter converts DC to AC, powers your loads first, charges the battery, and exports any surplus.
Battery stores the surplus
Excess solar charges your lithium battery bank for use in the evening or during a PLN outage.
Grid as backup only
PLN supplies any shortfall when battery and solar can't cover demand — and buys back your surplus.
Honest assessment
Pros and cons
Advantages
- Stays on during PLN outages — seamless switchover in milliseconds
- Battery stores daytime solar for evening use — reduces grid draw
- Optimise EV charging from solar generation
- Export surplus to PLN grid for bill credits
- Remote monitoring via smartphone app
- Future-proof — add battery capacity as costs fall
Considerations
- Higher upfront cost than on-grid (no battery)
- Battery cells need replacement after ~10 years
- Slightly more components to maintain
