Ive been looking at buying a 48v dc generator from Könner and Söhnen. https://shop.koenner-soehnen.com/en-pt/products/generator-ks-48v-dc In the spec sheet it says it charges at 70 amps which seems very high. My batteries are Pylontech 2x US2000 and 1x US5000. Am I going to damage the batteries...

Do they also supply in the EU?

As autumn is approaching im turning my thoughts to winter charging my pylontechs. Will my 3.5kv generator be enough to charge my batteries through a growatt spf5000es?

For clarity. Im in europe so its called earthing here, not bonding. ? We also dont use bare copper wire for anything, its yellow/green sheathed wire. And I'm using galvanised steel on a DIY rack.

I have those earthing lugs ready to install.

Can I earth each panel to the rail then earth the rail? It would save me many meters of cable.

Whoops 3s2p.

Panels are 38v open circuit, 18amps. 6 panels wired 2s2p.

Thats what i thought too but that would make it useless for my needs as each panel is 18a as it is.

I have a 48v system so 3200w or 150v. I understood that, it was just the 20a bit that had me scratching my head. Ive no need to over panel as this is a 2nd string which is over paneling my first string in preparation for winter. Thanks for the input, I will just make sure i dont go over 150/3200.

I have a renogy rover 60a charge controller that accepts 150v but in the specs is says the max load current is 20a. Does this mean my pv amps cant be over 20amps? Surely not. Im getting something wrong here....?

I just noticed one of the SOC lights is fading/half as bright as the others. Should I be concerned about anything?

A quick question to those more knowledgeable. I have a growatt spf 5000es and I want to add a second charge controller for a new string of panels. Will the new charge controller (Renogy) need to be communicating with the batteries (pylontech) the same as the Growatt is (port 1 to growatt)...

No. The output won't be used at all.
