Hello, I have a SPF 3000TL LVM-ES 3kW Growatt all in one. The unit it grounded, I have PV input (130-155v). It's not keeping up with the fridge in the cloudy weather, so I decided to add some help from the grid and plug it into the wall. However, I have voltage at the INPUT terminals for the AC...

I have the SPF 3000TL LVM-ES #kw and the input voltage is 120-250v. I'm averaging around the 135-155v input. I am looking for a second unit.

I took the picture before I removed the input plug. I checked the ground rod and the connection was a bit loose. Tightened that up and that fixed my voltage issues on the ground side of things. I still have around 25-27 volts between the ground and neutral or ground and line. since growatt...

Input is wired to input and output to output. Even with input wires disconnected I have voltage at the terminals. Doesn’t matter if the inverter is running on PV or battery.

No fix? Bummer. This is the second one I have ordered. The first one was all corroded. Guess I’ll contact the distributor and see if there is anything he can do. Thanks for your help on this. Happy new year!

1. I have the option of plugging into the grid. Main source is PV, I only plug into grid if the batteries run out of juice. 2. Yes, it was an extension cord/power strip that I cut. Polarity is correct. However the male end it hot. So somethin in the inverter is allowing current out the input...

Both numbers are just higher once batteries are connected.

Ground to ground voltage reading. If running on PV only it’s less at the moment. 72v ground in the input or output to grounding rod. 53v ground rod to line and neutral on AC input terminals and 53 v to line output to ground rod and 72v on the mitral output to ground rod.

I recently hooked up my system. Everything seemed to be going along fine. Then one of the kids touched the fridge handle while barefoot and got shocked to I did some investigating. My ground is putting out 112 +/- volts. I doubled checked the AC output and it’s wired correctly according to the...

Well, What's the verdict? It was a good read. Would love to know if the BMS did indeed need reset or if they were dead.

What’s the verdict?

These are commercial panels that I damaged are going for over $300.

I have the opportunity to purchase some unused, but damaged 385w panels. I am looking to get 56 of them. What would you gurus say is a reasonable offer? The back side works fine and he says no damage. Only the front side has cracked glass. Would need to fix if I want them to last longer. The fix...
