Thanks for sharing about your inverting biping. A couple options that may help: The Mecer 1200VA 1000W 12V W mppt Solar Inverter for R3279 seems well-priced and rated for your needs. With MPPT technology, it charges batteries efficiently from solar panels. Home Office Ups 300W Backup Battery Inverter Power Bank UPS-J300 for R3449 is also affordably priced and provides battery backup power, which may help resolve any biping issues caused by low power supply to your current inverter. Both come with warranty just in case. Hopefully one of these helps resolve the biping so you can stop worrying and focus on more important things. Let me know if you need any other recommendations!
