My father in law has a Renogy 2000w inverter charger hooked up to a battery bank and generator in his cabin. The inverter has an automatic transfer switch, which is controlled by software, to bypass and charge the batteries when it detects the generator is online. When I was there I noticed that when the generator is online the symbol indicating that the inverter detects the generator stays on but the transfer switch is cycling between battery/inverter mode and bypass/charge mode approximately every 10 seconds. Everything appears to be hooked up correctly and I checked through all the settings and couldn't see anything wrong so I'm assuming it's a software issue. Anybody ever have a similar issue and/or have any suggestions before I recommend sending the inverter back on warranty?
