When I see it now, I think I would like everything except the EG4s working as a backup with a manual or automatic switch, if possible. There are 2 battery racks of 6 EG4 48 Volt/100Ah each. 6 x EG4 LL 6 x EG4 LifePower

I add a drawing of the situation. The Generac generator is connected also to a switch, so that the Growatt can get either power from the generator or from the duel fuel mobil generator.

So the AC input of the EG4 would handle the AC output of the Growatt? I kinda like this idea, when it works.

Sometimes you could run into a situation (having air bnb guests, open gatherings) where you might be lucky, when a completely separate solar system provides you instant power. Also, when a EG4 unit fails, has to be repaired and I can't get a quick fix. So I am more thinking of backup system than...

Since I am planning to setup two buildings (cottage and workshop) with solar panels, I am running into a challenge, how to provide maximum PV input to my 2 x EG4 18kpv (not yet connected) in parallel as well as my already existing Growatt 12 kW with 24 x 300 W Canadian Solar panels in 4s3p mode...

Seems I just have to be patient and wait until the battery hits the setting to let the generator kick in. Hasn't happened yet, but the system runs without any issues.

Thanks for sending this information. I will double check that. The generator was hooked to a magnum solar system since 2 days ago and worked just fine. So I might think, that it should not be a generator issue. The crazy situation is, that the Growatt doesn't seem to send different signals...

I talked to Signature Solar today (where I bought the Growatt), but they couldn't help me with the situation. Still the dry contact in the Growatt stays open, no matter, what setting I choose. When I close the two contacts manually, Generator starts instantly. There is no voltage on the...

I hooked up my generac, which has the 2 wire start stop, to my Growatt 12kW with the dry contact (NC and C are connected to the wires) but for some reason the generator doesn't start after I drained the EG4-LL batteries a little to have the possibility to test the automatic switch function with...

I completely agree. There must be a reason, why signatur solar runs this hidden recall program for these inverters: Upgrade program I will try my best but I need a fast solution, otherwise I continue burning money through the roof, while using the generator 10 hours per day. There seems to be a...

Yes, main thing seams to be the update of the firmware. I will first install the new firmware on all devices tomorrow and see what happens. I'm not sure whether both cables (positive and negative) of the parallel installation of 2 battery racks, which are connected to an extra bus bar, are only...

Hi, I am new to this forum, have looked around but could find anything about the fault 80 in combination with the EG4 6500EX. I have a split phase setup with 4 x EG4 6500EX inverters, first 2 with a load center as Line 1 and second 2 with a load center as Line 2. First and second inverter set...
