Off-Grid Solar System
Full power independence, no grid needed
With batteries — for areas with weak grid supply.
Off-grid benefits
🔋
Battery backup
Use daytime power at night.
🌾
Villages & farms
Suited to remote locations.
⚡
Load-based design
Backup sized for loads and weather conditions.
How it works
Solar power is stored in batteries and the batteries run your home — no grid needed.
Step by step
- 1Panels turn sunlight into DC electricity.
- 2The charge controller fills the batteries safely.
- 3Daytime power is used directly and the rest is stored.
- 4At night or in clouds the inverter draws from the battery.
Good to know
- Batteries are required, so the cost is higher.
- Size the battery for nights and cloudy days.
- There is no export credit to the grid.
Best for
Remote homes, farms and farmhouses, or places with a weak or absent grid.
Planning a dependable off-grid supply
Define essential loads first
List lights, fans, refrigeration, pumps and other appliances with their wattage and daily operating hours. Consider simultaneous demand and motor starting current separately from energy use. Backing up an entire property for a long interruption requires much more storage and expense than keeping a small set of essential appliances supplied.
Battery capacity and inverter power are different
Battery capacity in kWh describes stored energy; inverter power in kW describes the loads it can support at once. For example, a 500 W load running for four hours uses 2 kWh before losses. The nominal battery must allow for conversion losses and its permitted discharge limit. This arithmetic is a planning example, not a final equipment recommendation.
Compare lithium and lead-acid storage
Lithium and tubular lead-acid batteries differ in usable capacity, weight, maintenance and charging requirements. Comparing amp-hours alone is misleading without voltage and permitted discharge depth. Check inverter compatibility, temperature limits, ventilation or enclosure requirements, warranty conditions and future replacement costs. The most appropriate chemistry depends on the duty cycle and installation conditions.
Design for cloudy days and overnight demand
Energy used from storage overnight must be replenished while daytime loads are still operating. Several cloudy days can reduce available backup. Discuss reserve capacity, essential-load priorities and any alternative charging source. Off-grid independence is conditional on the generation and storage design; no finite battery guarantees uninterrupted supply under every weather and demand condition.
Match remote and farm applications to the task
Pump design depends on water depth, flow and irrigation schedule. A household battery package is not automatically suitable for an agricultural motor. Remote sites also need security, service access and safe equipment housing. Do not budget an off-grid installation using assistance intended for eligible grid-connected residential rooftop systems; agricultural schemes have their own conditions.
Common questions
How many hours of backup will I get?
Duration depends on usable battery energy, connected load, losses and state of charge. Request a calculation based on your actual appliance list rather than a blanket hours-of-backup promise.
