July 14, 20233 yr My setup is as follows: Mecer SOL-I-AX-3Mplus48 Sunsynk 5.32 Battery 4 x 555w panels in 2 strings of 2 Solar Assistant Having installed Solar Assistant, I'm following the load and battery state to get a feel for how I want to set the inverter modes. I notice that the load measurement seems to drop to 0 every 15 mins or so for about 15 mins, then jumps up again. The load is not actually changing, but it appears that the inverter is measuring g it as such. Will a firmware upgrade sort this out?

I very much doubt it, but please post your present main (U1) firmware version so I can check if there is a later firmware. That sounds like hardware to me. Edited July 15, 20233 yr by Coulomb
July 15, 20233 yr Author @Coulomb, it's 02.68. I read on another forum the Mecer show zero load if the load is below 100w. This was in the early hours of the morning, so it could be the load dropping to the base load of a few lights and electronics in a resting state. The lights were still on, though, so the inverter was producing power.

July 15, 20233 yr Author Weird. Not sure how it would have been updated.... I have connected it to Power watch twice to configure it. To my knowledge it was a used unit prior to me getting my hands on it in February this year...??

I don't see that in the firmware, though that 8-bit processor is hard (for my brain) to follow. Certainly my PIP-4048MS (Axpert MKS 5K-48 PF0.8) will display right down to low, presumably even one, watts.
