Solar inverter on generator or on battery inverter?

[sicetaitsimple]

The solar injected 136 W,
the voltage of the voltage limiter is at 226V,
the loop charger was plugged in and took 350W (in addition to the fridge at 160W) so all the solar energy was used with a coef of 3!
the voltage of the simulator at 228V...
the voltage of the simulator connected to the PV during the synchro and therefore before injection was at 224V

The inverter condo slammed when the charger was unplugged, a few minutes later...(fridge shutdown??)

I did 2 tests of about 30 seconds of self-charging loop and as I said before, when I stopped the charger I heard boiling in the inverter...may be precisely because of the rapid rise in voltage due to the disconnection of the 350W?

"Inverter condo banged when charger was unplugged,"

It only reinforces the interest of a test where you would be sure that the consumption is always higher than the PV production.

Yes it is noted! Plus a synchro bulb!

And in my opinion you have to leave your self-charging loop permanently connected, without trying to disconnect it (big sucks...), it ensures a "minimum flow" in your sinus inverter. If it works without unplugging it, it will be the subject of a next test to unplug it.
Well, once again it's electricity seen by a hydraulician (basic).
But it's just step by step that you will know what is possible, or not, avoiding if possible to burn an element at each test.

Yes it is possible but the "bubbling" (in the condo therefore) when I disconnected the self-charging loop frankly worried me...

It stopped after about 10 seconds...

ps: big con

All the more reason not to unplug it!

Except that, it was bubbling maybe even more when it was loading!!!

I said it several times above I heard nothing because of the fan of the charger!

Anyway it's not the solution because the maximum solar power is 10 times greater than that of the charger!

You should know, it was bubbling more or it was bubbling less?
You do as you want....

What I'm just saying, from your photos, is that the 230V socket on the back of your inverter seemed, if I understood correctly, to supply the charger which recharged the batteries connected to the inverter in question.
Certainly, it is a system which, isolated, is not very efficient! It goes around in circles generating losses (see my post on page 2).

But hey, if it's an operation that allows the sine wave inverter to operate correctly by giving it an almost constant basic consumption, why not.
It remains to be seen whether it will react to consumption demands when it is in parallel with the solar inverter.

Reread above I think there is about 50W of loss…not very efficient but better than a blackout or a generator!

For the noise… Are you hard of the sheet or are you clogged?

a) I could not hear a possible bubbling, low noise, during charging because of the fan of the charger…

b) it was bubbling about ten seconds, maybe less (5 seconds?), after stopping the charge...that's all I can say...

Well, you don't know if it tickles you or itches what...

The inverter, well, he's knocked out...

[Christophe]

Completely useless post...one more!

He will recover from his technical knockout, don't worry!!
