Chargeverter & Deye SUN12kW S04LP3

[Bossman253]

I have Deye and Chargeverter. Inverter is connected to batteries with JKBms without com communications, Inverter is setup to read voltages from battery (coms jkbms in early stage has many bugs with deye)

So How do i charge batteries properly with chargeverter so that deye will get proper readings from batteries. Otherwise deye will get false readinngs from battery when i turn on or off chargeverter.

Is there any solution for this ?

It shouldn't be very far off. As long as you connect the charger at the battery, and not the inverter terminals.

Inverter terminals for Bat+- are same as BMS terminals. Just couple cm in diff direction. I am saying about something different if you carefully read my post.

If they are that short, it really won't make a difference.
I don't know what problem you think you have.
When charging, the voltage rises. This is the same, whether the charging comes from inside the Deye or from another source.

Is the error direction here harmful? It will raise the voltage which if you are using voltage cutoff will cause Deye to stop charging.

When you’re using a chargeverter you are already willfully doing manual charging control, vs the automated control in the Deye. And I’m not sure you can expect the chargeverter to share charging load evenly with another charger, that is not one of the design goals and requires extra coordination.
