First question on the forum so be gentle with me!
Recently due to rising UK energy prices I built an off-grid "Solar Generator" using a 405W panel, MPPT 100/30 charge controller, 24v/500W Phoenix inverter and DIY 7s10p 24V 18650 Li-ion battery... all worlking as intended. The battery is charged during the day, and its used to run appliances and charge things during the night.
I would like to use the same panel with a small G98 certified grid-tie inverter, so that once the battery is charged each day, the panel connections are automatically switched from the MPPT 100/30 charge controller, to the grid-tie inverter.
Can I use the TX port of the MPPT 100/30 to trigger some sort of 2-pole relay, that would allow the switching of the pv + & - from the MPPT CC to the grid-tie inverter once my battery is fully charged? Do I need to use a Smart Battery Connect somehow to make this work?
Any help would be greatly appreciated.
