Load shedding hasn't gone away — it's just intermittent. A well-sized inverter and battery system keeps your essential loads running through stages 1–6 with no audible generator, no fuel, and PV-ready for future solar. We size to actual measured load — not the marketing spec sheet.
What we do
Energy audit, inverter and battery sizing, essential-loads board install, inverter and battery mounting and connection, monitoring setup.
Inverter sizing guide
Match the inverter and battery to what you need to run.
