Set these two Growatt SPF 3000TL LVM-ES inverters up off grid. I had the “master” set up on its own a month ago and I added the “slave” yesterday. They’re set up in parallel (PAL) mode for 120v.
What happens is the slave voltage increases when I flip the master breakers on, the slave immediately goes from 120v to 130v - 140v.
They’re both sitting at 120v without a load, but when I flip on the breakers and I add a load the slave jumps up to 148v. Just doesn’t seem right. I haven’t tried running a load on the slave’s breakers, however the GFCI outlet lights come on green for those two slave outlets.
On the main panel box, the master feeds L1 and slave feeds L2. All grounds and neutrals are connected on two bars tied together.
Any help is greatly appreciated. The panel box is the 100A homeline 6 pole.
