Is it possible to limit or control AC voltage output

Q&A and troubleshooting

In France AC voltage is 230 +/- 10% (i.e. 207-253) and I’m often 250V and this may be causing issue to my heat pump. The primary pump has a protection for surges and may not run if voltage is too high. When there is no sun and battery is empty, the grid voltage will often drop when the heat pump starts allowing primary pump to run. Less so when it’s sunny or battery full as the inverter will help maintaining the grid’s voltage to 250V.

Is there a way to configure my Easysolar, set up as grid-parallel, to only maintain let’s say 240V max instead of matching the grid ?

I see there is P(U) response configured as
V1 90%Un, V2 95%, V3 110% invert power is 100%
v4 112% invert power is 0%
but that seems to only apply to feed in. Is my understanding correct?

I don’t feed in and I want it to apply only to my home when grid is present

No it is not an AVR

No, the easysolar has no influence on the output voltage as long as you are connected to the grid.

The only way you can manage this is by taking the easysolar from the grid, use a separate 230V charger to supply your “off-grid” system.

This is not possible. Have a look at the block diagram in the manual, copied below, ac in and ac out are directly connected so you can not control ac out when connected to the grid. The EasySolar only has one dc/ac converter which is bidirectional.

But ofc you can set the acceptable input limits of the Multiplus lower, then it will disconnect by itself and keep your appliances safe.

Set your ac high disconnect to 245V, your high connect to 240…

But then you might have to buy some additional batteries
