Edited the post to be more clear. There are 2x batts in parallel with 400A of peak discharge capability

Can you explain this one in more detail? How long does it take to bring the compressor back? Best way to dump setting here?

The eg4 power pro battery. 2x of these have a peak discharge capability of 400A or ~20kW. The panels at the time of testing were putting out >5kW I thought it may be the startup current issue even with the soft start and that is why I tried starting with the grid and then turning off the...

I have run almost 1MWh through the 18k+ 2x PowerPro (400A, 20kW peak) Batteries + 18kw panels and it’s been working great (mainly off grid). Now that we are hitting a couple hot days in Texas I have tried to use my 4ton lennox xp21-048-230-04. It will not run while I have the inverter...

This seems looks similar to my thread here. https://diysolarforum.com/threads/growatt-spf-6000t-output-voltage-cycling-while-on-only-battery-input.73290/#post-931390 I am emailing signature solar and will let you know what we figure out

No, this is in “Inverter On” mode. I expected it to be something to do with powersave and have swapped back and forth between the 2 modes with no change.

Hi, All I’m having trouble with my growatt SPF 6000T DVM while it has no inputs other than the battery. While only batteries are supplying power and the switch is flipped to “Inverter On” the inverter output ramps up to the expected 230V output stays there for ~1s and then ramps right back down...

Here is the link to the inverter at signature solar where I got it. https://shop.signaturesolar.us/products/6kw-48w-150vac-80a-off-grid-inverter-by-growatt I live close enough that I went and picked it up at there east Texas location. They seem to be good people. The manual is at the link as...

Hi Bob, I was able to modify setting 21(low bat cutoff) by switching to USE. I am still not able to get the generator to stay on. It is still looping on and off. I think this may be from the generator frequency going out of sync when it is first loaded. I am going to try to reduce the utility...

Okay, I think I may have found a way to solve issue 1 - not sure how it will affect the second auto start problem. I will change to the "User-Defined profile and then setup new self defined settings for 19, 20,21. Changes here: 5: USE 19: 58.4V 20: 54.0V 21: 48.0V My question here is how do...

Also if I manually tie the gen auto-start wires together the generator will crank, supply the load and charge the batteries. This seems to tell me it is something with my settings on the cut off and on voltages.

I have hooked up a growatt SPF6000T DVM. This is connected to 2kW of panels on the PV input(90V when loaded), 2 banks of 48V 200Ah flooded golf cart batteries, and then I have the AC input connected to a Kohler 6kW generator with a 2-wire auto-start system. The solar and battery charging...
