18kpv - house load does NOT always take priority

Ok, so I was always under the impression that the 18kpv would always under any circumstance provide load power to the house if power was available.

Well, not so. I was able to make the house shutdown completely even though there was enough pv getting generated.

It seems when your battery is low and the bms is in “forced charge” mode it overrides everything including powering loads 😳

Ok for EG4, so they can easily reproduce the scenario

1. I am on firmware 2122.

2. Have battery low below 5% so bms is in “forced charge” mode.

3. Have offgrid mode enabled. I am still physically connected to the grid.

in this scenario, the 18kpv will

a. Send all pv up to your charge limit to the battery, BUT 0w to load. It will curtail the incoming pv to the charge amp limit set and NOT send any extra to the load even if more pv is getting generated to satisfy both battery charge and load. So if I have it set at 30a charge it will send 30a to charge the battery and nothing else. If I set it to 10amps then it curtails the pv to only satisfy said 10amps.

b. While (a) is happening, it switches me from “offgrid enabled” to “offgrid” disabled (without changing the actual setting) and uses the grid to satisfy the loads. It will also use around 700w from the grid to help charge the battery is say I have it set to charge the battery at 40amps and only 20amps is coming from pv. I might also add here that my charge from grid is disabled.

i went so far as to switch the grid breaker off to see if it would use the pv to satisfy the loads. Guess what, the house lost all power. The house was using 1000w, pv was generation 2000w and all going to battery.

yes an interesting scenario, but loads MUST always no matter what take priority. NO MATTER WHAT.
