Hi there, here in the Netherlands we have the issue that a pv-inverter turns itself off when the voltage is too high locally, in my neighbourhood it happens too much. If I move my inverter behind the essential loads, would my multiplus be able somehow to keep the voltage lower, so my inverter can continue? ( I know a Victron mppt could be a solution, but I have 24 440Wp panels in 2 strings, so mppts would be some work here:) I’m curious what my possibilities are
Hi, no grid voltage is multiplus voltage…
The multiplus will also throttle down grid feedback when grid voltage is too high
Mppts can be an option, but multiplus grid voltage behaviour will be the same, because these are the grid rules in NL
All you could do is let the multiplus disconnect from grid when voltage is too high, but if batterys are full and load is supplied, the multiplus will throttle the ac inverter or mppts and there also will be no grid feedback at all
Try to charge your batteries with the ac pv power keeping the grid to 0 watts. This will lower your voltage a bit, possibly just enough to keep everything running. Dess green mode should do this for you most of the time.
Also see my topic about P(U) setting in veconfigure preventing the victron when it is discharging when the grid voltage is to high.
Some pv inverters can also be configured to ramp down there output power before disconnecting from grid btw.
