Multiplus II GX 3Kw with critical loads but only using current sensor. System works well.
ESS parallel with 2 pylon @ 7Kw/h. A distributed solar system with multiple microinverters half on L1 in and half on L1 out (critical load) total of 4Kw/p
Excess is switcht to various uses (openhab) e.g. hot water the excess is fed into grid. Grid set point variable mostly @ 60 watt.
Interestingly both dashboard and remote console display do not show negative flowing from L1 out to grid or charger. but remote device list shows L1 in and L1 out with negative.
Also I observed a switching Hz info L1 stable on 50.1 - L1 out switching 50.1 - 49.9
Pls note snipets are examples only figures do not match as not taken at same moment
