PV Inverter Frequency

Hi guys

I’ve wired up a PV Inverter to the output of my MP2 and configured the settings through PV assistant

I also have PV chargers in the system but seems as when the PV chargers start charging the frequency rises on the multi which stops the PV Inverter

Battery has plenty of room to charge and there’s at least a 1kw load on multi

Why is the frequency rising and not allowing the PV Inverter to charge

You need an energy meter to see the production from the PV inverter. There are 2 settings that can stop the PV inverter.

One of them is in general, if this is not 100% or 95% the multi will raise the freq and stop the PV inverter.

Also what happens when you disconnect the PV chargers?

The second is to enable charge and charge current. Its the internal charger that will charge the battery if this is not enabled then it will not charge.

Check these first.

Thanks Owen

After looking at your pictures I realized a missed step when setting up
I had the wrong Absorption and Float voltages set

I have them set correct on PV chargers but not in the Multi

Also, I am going to add a shelly device and integrate it with the cerbo using Andy from off grid garage

Thank you for your help
