Growatt 6000. Output voltage

[Demoman]

I can’t download the manual for the battery, they used a shifty label that rubs of when you touch it. Too blurry to read

Wouldn’t you want the battery to recharge when the power is present to recharge it regardless of the power remaining? Doesn’t make sense to have a back up battery sitting at 60% when the power fails wouldn’t you want it at 100% ready to go?

What you want isn't relevant. How the equipment works is what you get. Please provide the exact model of Growatt inverter.

The generator I’m using doesn’t seem to move much more than .5 hz

Starting on page 18:

01: SBU is generally the preferred mode.
02: Set to 140A
03: APL
05: USE
06: Lfd
08: 240
09: 60
11: 30A, but you may need to set this one to 10A and increase it slowly depending on the quality of your generator power.
12: 51.2 - this is the highest setting.
13: 56.8 - cut AC charging when battery is very near full
14: SNU
15 - 17: your preference
19: 56.8V
20: 54.0V
21: 44-48V your preference
23: d1S

You have selected an inverter with an atypical AC charger. It is like a tank float valve - ON when it drops below a certain level and OFF when it rises to another level. It will ONLY charge when the battery voltage is below the voltage specified in setting 12. (51.2V) It will stop charging the instant the battery reaches the voltage in setting 13 (56.8V).

The generator I’m using doesn’t seem to move much more than .5 hz

That's likely going to be a problem. 0.5Hz is not great. Growatts are picky. Suggest you change setting 11 to 10A and slowly increase it until you hit the max it can handle, and it won't charge anymore. If the generator is portable, recommend you get it as level as possible.

I believe if you turn the inverter off and place in standby mode, it will charge via AC even at higher battery voltage, but I'm not certain.

Note that when charging via generator the generator is also powering all loads and the charger, i.e., if your loads + charger is greater than your generator output, it will overload the generator.

Wow, thanks for all that, you the man. I don’t think I would have figured all that out on my own. I am in your debt sir.

I’ve got 4 / 200 amp hour Renogy batteries set up for 48 volt since my inverter is a 48 volt 6000 watt split phase

This was before I had changed my inverter on the left side to 48 volt Growatt the other 2 I had bought never worked

Where are you located? USA?

I’m in Ontario, I would like to add a turbine next. Solar would just get covered in snow. 48v turbine is $1500. Maybe a little more

Wind or hydro?

Rule 1: The power rating of a wind turbine has NOTHING to do with the amount of power you'll get. The amount of power you get depends on the size and efficiency of your wind turbine, and your wind. The power rating of a wind turbine is just its...
