Off-grid solar
Total energy independence from the grid
No PLN connection required. Generate, store, and consume your own solar energy entirely — ideal for remote villas and eco-retreats.
How it works
Solar panels, batteries, and nothing else
- Solar DC
- Battery DC out
- AC to loads
Panels generate DC power
Solar panels generate electricity from sunlight. Bali's 4.5 peak sun hours per day makes this highly effective year-round.
Charge controller optimises charging
An MPPT charge controller extracts maximum power from the panels and charges the battery bank efficiently.
Battery bank stores energy
Lithium iron phosphate (LiFePO4) batteries store your solar generation for use at any time — day or night.
Inverter powers your property
A pure sine wave inverter converts battery DC to household AC power. All your appliances run normally.
