Frequently Asked Questions
What is an off-grid solar kit?
An off-grid solar kit contains equipment intended to generate, manage and, where battery storage is included, store electricity without relying on a permanent grid connection.
The exact components and capabilities vary between kits.
Where can off-grid solar kits be used?
Depending on their size and design, off-grid systems may be considered for cabins, workshops, garden buildings, remote properties, campervans, boats and other locations where mains electricity is unavailable or impractical.
Suitability depends on the electrical loads, installation location and complete system design.
Can an off-grid solar kit run household appliances?
Potentially, but this depends on the specific inverter, battery and solar array as well as the appliances being used.
Important factors include continuous inverter output, surge capability, battery usable capacity, daily energy consumption and expected solar generation.
A system should be sized around the actual loads rather than appliance type alone.
Why is battery storage important in an off-grid system?
Solar generation varies throughout the day and with weather conditions.
Battery storage allows some of the energy generated by the solar array to be stored for use when solar generation is lower or unavailable.
The required battery capacity depends on energy consumption, usable battery capacity, desired autonomy and whether another charging source is available.
How do I choose the correct size off-grid system?
Start by estimating:
daily energy consumption in Wh or kWh;
maximum simultaneous load;
appliance starting or surge requirements;
required battery autonomy;
available space for solar panels;
installation location and orientation;
and expected seasonal solar generation.
Winter conditions are particularly important when designing an off-grid system intended for year-round use.
Can a backup generator be connected?
Some inverter-chargers support a compatible external AC generator input.
This is product-specific. The generator and inverter must meet each other's voltage, frequency, power and connection requirements.
