I control two SolarFlow 800s with the ZHA Integren and MQTT.
I had the following questions regarding this:
(1) If the house requires 250W, the HEMS distributes this over 2x125W, whereas I allocate this to 1 inverter for efficiency reasons. Is there information available regarding the minimum input/output that does not compromise the inverter's efficiency?
(2) To avoid shortening the device's lifespan, one wants to switch the relays as little as possible. Does this mean you should avoid switching unnecessarily from input to output (and vice versa), or does a relay action also occur when switching from input/output to zero energy? In that case, could I artificially keep the energy flow at +/-10W when it is actually 0W? Is there information available on this? (Zendure Home Assistant Integration 1.3.1 with Solarflow 800)
