Forrest we have 2 multiples II configured split phase, 2 250/60 mppt solar chargers victron smart buss and cerbo with touch screen and 4000w of solar but if your plugged into the grid on a sunny day it will not utilize the solar so if your in a campground that charges for electric your screwed. I've been on DIY solar forum and followed people like us have tried everything to get the system to turn off the grid when the sun is out and you sort of can do it with a virtual switch but NOT effectively and also selecting inverter only which will force the system off the grid but if you forget to turn it back on you'll run your batteries down. Growatt is simple all in one and will use solar first as long as the sun is out.

Thank you for the email address!

Although I have generally sized my system of 2 Victon Quatto's for off grid use, couldnt you change the system setup process a little bit to reduce the max line current you pull from grid 24/7?

In operation, lets just say you use 2500W average all day long.  If you programmed your grid to only deliver a maximum of 1500W, you could cycle your battery a little bit, use your solar to charge your battery during the day and drained it during the night down to some reasonable level where you could then take in the solar power during the day.  

If you error on the side where you charge your batteries to full before the end of the solar day you could take in maximum production.  

Does this balance sound reasonable?
