Off-grid safety requirement
Load Segregation
Critical loads separated from heavy and comfort loads.
Off-grid systems perform best when essential loads are separated from heavy loads. The inverter and battery are then sized for priority circuits instead of every appliance in the building.
Why It Matters
Separating loads keeps backup stable for lights, fans, routers and essential devices.
Heavy motors, ACs and pumps can drain batteries quickly and create high surge demand.
Clear circuit planning prevents accidental overload after handover.
Required Checks
Appliance list with wattage and daily running hours.
Critical, comfort and heavy-load grouping.
Motor, compressor and pump starting surge.
Dedicated inverter-backed circuits and bypass/non-backed circuits.
Future load growth allowance.
Required Documents
Load audit sheet.
Critical-load priority list.
Circuit segregation plan.
Inverter output distribution note.
Customer approval of backed-up and non-backed-up loads.
Installation Details
Mark inverter-backed circuits clearly.
Keep heavy loads outside backup circuit unless specifically sized.
Use suitable AC protection on inverter output.
Explain load limits to the customer before handover.
Handover Records
Final backed-up load list.
Expected backup hours for selected load.
Circuit labeling photos.
Customer operating guidance.
Service Notes
Recalculate before adding AC, pump, compressor or heater loads.
Track overload trips and user load changes.
Review backup performance during seasonal usage changes.
