Hello,
I've got China's HPS 3KVA inverter: https://pl.aliexpress.com/item/1005002546425884.html with no dry contact.
Has anyone tried to add a dry contact switch by yourself?
I would like to solder the wires on the motherboard to be able to detect when the inverter works from solar panels or on a battery.
(when the device works on batteries or solar panels, I would like to turn on the water heater - 230V AC)
Motherboard
Thanks
