Solar amount

Curious I hooked up a 8 panels in series. I am only getting 210v, 1.0 amps, 206 watts... This isn't right or is it?


I did this just get some power to charge the batteries until I get the whole system hooked up.

Check for loose connections.

What inverter?

 

[chrisski]

What time was the 200 watts. Since sun is setting in an hour where I am, that could be reasonable.

Was it sunny?

It was about 230-3.. it is a LVX 6048.. I'm hooking it up for my neighbor..

Tim if was a loose connection, it wouldn't read at all? Or would it?

 

[chrisski]

My loose connections have been loose screws on circuit breakers and bad crimps on Anderson plugs. Also nuts working themselves loose.

These can show up as heat loss. The voltage goes somewhere.

Load breaker open?
Battery full?
Set to export?

I'll check tomorrow. I have to read up on this manual as it's different than my growatt.

On those 8 panels, what should the voltage, amps, etc read?

So you have panels with a pmax of just over 30v and you have 8 hooked together in series and you are getting 210v instead of 240v which is 30v short of what it should be. Could it be 1 of the panels is defective causing problems???????

I have never understood the amp, volts etc in series.

So I should have 8x30=240v, 8x8amps=64?, and wattage 250x8=2000?

In series amps stay the same 8 and volts multiply 240v
In parallel volts stay the same 30v and amps multiply 64 amps

 

[Traviss224]

Thanks what about the wattage?

 

[Robert Ibe]

Thanks what about the wattage?

You got the wattage right.

 

[Traviss224]

So I have to figure out the why all 8 isn't showing up

yes, a loose connection will cause the voltage to complete the circuit by jumping (arcing) the gap.
A loose connection will limit the current flow.
So any load can easily pull the voltage down.
Turn off the charger and see if the VOC is what you would expect.

I have to correct myself.
I misread the first post.
I thought you were seeing 110v. Which lead me to the loose connection.
But 210v is 87.5% of the specs. (Perfect lab conditions)
Right about what I would expect, with a 1a load.
It appears that your system doesn't need any more than that, at the moment.
You can verify this by increasing the loads (turn on some appliances).
If the production increases, everything is working correctly.

It looks like it just didn't need the energy. Today the batteries were presumably pretty dead and it charged those good
