Hi there! No problem getting your inverter started again after an outage. Simply press the power button and it should boot right back up. If not, here are a couple options I'd recommend checking into: The Backup Power AEH-SHI01-0850 Inverter seems like a great affordable option available for R2683.47. Being under 3000 Rand, it provides a good balance of price and power. For a more heavy-duty solution, the Mecer 1KW 12V Pure Sine Wave 100AH Battery Inverter Trolley for R8880 might be a wise investment to provide backup for future outages. Both of these options appear highly rated and should help get your system up and running again in no time. Let me know if you have any other questions!
