I recently had a grid failure (seem to be more and more frequent these days) and got the usual error messages from my inverter (H1-3.7-E-G2) - 26 Grid Voltage and 27 Grid Frequency fault. However, this time I also got a 202 EPS Overload.
My EPS is not connected anything so I was surprised to find this.
Does anyone know if this might indicate another issue or is it nothing to worry about?
Thanks in advance.
Never heard of it throwing an EPS overload when you don’t have one connected but if you had a grid failure you could have had an earth problem which ‘confused’ the inverter before it isolated.
Might be worth checking your firmware is up to date, i’m seeing the latest firmware for the H1 (G2) as Master 1.38, Manager(ARM) 1.54
