@Stan Flowers I have seen reverse polarity made on an mppt from the pv side with the battery connected correctly. It had been like that for several hours. All that happened was the unit

Reversed polarity outlet issue | DIY Solar Power Forum

Reversed polarity. Many Chinese wired inverters have suffered from the problem. While not operating in AC bypass your unit would have to have a means of bonding neutral. It would also

How to reverse solar panel polarity safely for testing
