Does anyone have experience with a micro inverter WITHOUT a communication option? Is only the wifi module missing? These inverters are considerably cheaper, because the prices of micro inverters are currently rising considerably in the Netherlands. I am able to build something alternative via a ttl/rs232 interface… My goal is to compensate only my standby consumption (±100W) with 1 solar panel. And that also at night by means of a 24V battery, but then with reduced inverter output (100W instead of 400W). See item on my website: abuse.nl.eu.org/SOLAR .
