What is an off-grid inverter?

An off-grid inverter converts solar DC power into AC power. It supplies your home or business directly from solar panels and batteries. It operates without any connection to the Eskom grid. All power comes from your solar panels and battery bank.

Can I use an off-grid inverter if I have an Eskom connection?

Yes, but a hybrid inverter is usually better in that case. An off-grid inverter does not connect to the grid at all. For both grid and solar power, a hybrid inverter is the right choice.

What size off-grid inverter do I need for a farm?

A 5kW to 6kW Luxpower off-grid inverter covers most small to medium farm loads. Larger farms with three-phase equipment need a 3 phase inverter instead. SP-Energy offers free system sizing for all off-grid applications.

What is the SRNE All-In-One system?

The SRNE All-In-One packs an off-grid inverter and built-in LiFePO4 battery into one compact unit. The 3.5kW model and 5kW model are available at SP-Energy. These suit simple setups where space is limited.

Do off-grid inverters work with any solar panels?

Yes. All off-grid inverters in our range work with standard monocrystalline and polycrystalline solar panels. SP-Energy also stocks JA Solar, Jinko, and Longi panels to complete your off-grid system.

Where can I buy an off-grid inverter in South Africa?

SP-Energy stocks off-grid inverters at 7 warehouses nationwide. Collection is available in Vanderbijlpark and Midrand in Gauteng. Contact us to confirm stock and get a free system quote.
