5 kW off-grid PV system
In an off-grid system, the available energy is limited by seasonal generation, battery capacity and inverter power. Sizing starts from the loads that genuinely need to be powered.
No off-grid configuration guarantees unlimited autonomy; weather, temperature and the consumption profile all change the outcome.

Calculate the autonomy
Convert consumption into kWh/day and keep a realistic reserve for days with low generation.

Components for assessing an off-grid system
This selection is a starting point. For off-grid operation, the backup/EPS function, surge power, battery compatibility and behaviour without the grid must be explicitly confirmed.

Data required for sizing
The more accurate the inventory of loads, the lower the risk of shutdowns and the cost of oversizing.

Clear answers
Questions before you buy
These answers explain the commercial and technical limits of the choice. The product specification and the confirmed quote remain decisive.
Can a 5 kW off-grid system power an entire house?
It depends on the loads, simultaneous use and the energy available in the battery. The 5 kW rating describes only part of the system and does not guarantee the energy needed over a full day.
How many kWh of battery do I need?
Capacity starts from the daily consumption that must be covered without sun, then is adjusted for usable energy, temperature, losses and a safety margin.
Can I connect a backup generator?
Only if the inverter and the project design provide for this function. The input, automation and operating rules must be checked against the equipment documentation and by a licensed specialist.
Do the products on this page form a ready-to-install kit?
No. They are relevant components from our catalogue. Protection devices, cables, mounting structure, number of panels and battery configuration are determined separately for each project.
