I seem to be unable to configure what I was told the EasySolar could do. It’s possibly my fault, but if not it’ll be a feature request that I think would potentially sell a lot more victron units in Australia.
If one selects “grid code” of “none” it seems I cannot use PV power unless in powerassist mode, UPS (in Ac-in fail) or batteries need charging mode. Ie under normal operation (grid/generator present) PV power will reduce as the batteries charge, and even though I have 1.6kw of panels I’ll see charging of just 20w etc.
ESS cannot be started with a grid code of “none”
ESS cannot be started using the Australian grid code (it warns that a secondary relay is not present in the product)
Selecting UK (and others) will allow the ESS to start and one can then select “use excess PV power to feed into the grid” which then will use all PV power available (Which majority of the time is lower than the load).. but obviously this would be non compliant (and therefore illegal) if running without an anti-islanding relay.
I have also noticed I have to set “keep batteries 100% charged” for it to work, using “optimized” will cycle the batteries.
Setting “power assist” will work sort of... if I set the limit input to 4.5A it will use a couple of hundred watts to power the load, however it will never use less than 700w no matter if I set the input limit to 0.5A... (it just sets itself back to 4.5 in the GX) ... and worse (for my situation) should the load go over the available PV power it’ll discharge the batteries.
So nothing does what I want to do.
I want to use the easy solar as a UPS and have the PV power reduce grid power. Ie:
I have “cranker batteries” (24v 200Ah flooded flat lead plate) so they should be just used when there is a grid failure. Grid is stable for most of the year but I have a lot of computers hence needing/wanting to use “UPS” mode. I do not want to feed any power into the grid,.. just downstream to the loads. If there is excess PV power after the batteries are charge and the grid consumption hits zero just reduce the output of the MTTP charger. (This is got local regulations compliance... domestic premesies are not allowed to feed in more than 6kw of power.. which I wouldn’t anyhow, but as a consequence no installer will install greater than 6kw without an upstream limiter and non seem to want to do Victron stuff.. so I’m installing them (EasySolars) as UPSs for each power rail in my mini DC.. i’ll End up with >6 of them and 18kw of panels if they can actually do the job I need.)
