For sale is 1 x Pylontech US3000C brand new in sealed box (warranty replacement). Cape Town area. R13k Age: New Price: R13k Payment Method Accepted: EFT Reason: Not needed anymore. Shipping: Yes - at buyers expense.

Thanks - not really sure how to unset it so changed it to 50A. Leaving it at 25A I only get about 1300W charge when set to KEEP BATTERIES CHARGED. Goes up to about 1900W when setting that to 50A.

Hi all I just added a second Pylontech - now got 2 US2000's. I'm running ESS. Can I change Maximum charge current to 50A? Any other settings that needs changing?

Installed one these now. This thing is a monster 😃

Put 240AC on the thing and still doesn't switch - its going back. Thanks all for the help.

My fault - I ordered the wrong thing. So now I'm looking at: https://www.communica.co.za/products/jqx62f-2z-dc12v or https://www.communica.co.za/products/jqx30f-2z-dc12v-flange These are the only two 12V coils in stock. I'm leaning towards the first one as its heavy duty especially as this is for a geyser application. What you think? 3rd time lucky? 😁

I ordered JQX-40F https://www.communica.co.za/products/jqx40f-1z-ac240v. I can see the coil inside is labelled AC240V. These specs http://langir.de/htm/power-relay-jqx40f.htm say Coil Voltage DC 5 ~ 60 😕

Thanks just tried that - no cigar.

Damn - OK I thinks its safe to say this thing is dead. Gonna have to return for a replacement.

Must there be 220V connected to the switch for the 12V over the coil to actually make the switch move?

Yup - except looks like its an out the box failure unless I'm doing something silly 🤔

Thanks 12V no problem. The issue I'm having now is with testing this thing. If I put 12V over the coil I would expect the mechanical switch to move - it doesn't. Nothing else is connected just a 12V battery over the coil terminals. I'm using a multimeter to check for continuity. No change with 12V on and off.

Hi all I got one of these http://langir.de/htm/power-relay-jqx40f.htm Could I please get some help as to how to wire this up to my geyser using the 5V of the VenusGX as a trigger. Thanks!

I did not use a heatsink obviously I should have. I've ordered one of these now https://www.communica.co.za/products/jqx40f-1z-ac240v

Right - did the research this time. Looks like electromechanical relay is the way to go for this application.

Removed it - the plastic housing started to melt ☹️

Man this relay gets hot - seen some reports of the thing melting online. Think I'll look for something else. Any suggestions? It's powering a 3000W geyser.

Not really - this was the first one that was available at a reasonable price.

OK got it - working on the 5V.

Actually I'm probably wiring this totally wrong. No idea what I'm doing 😀 Cable to left is connected to nothing at the moment. Venus reboots the moment I plug in the Relay and 5V power plug (nothing other end)

Overloaded indeed - thanks will try the external 12V again 🙂

Hmm - so using the 5V power out and turning the relay on actually reboots the the Venus GX ☹️

So no idea what that little relay draws in my photo above. I'm assuming it just needs something small to tell it to switch on and off.

Thank you - missed the 5V out on the Venus! So no need for the 12V supply then....

I got one of these to attach to the VenusGX as I want to control when my Hot Water Geyser comes on. Any tips to wiring it up? From what I can tell I need to use a 12V Power supply connected inline with the Venus relay. When the Venus relay is activated the 12V will activate the solid state relay and vice versa. Anything else I need to do? I tried a test run and it all worked fine except when the Venus relay was OFF the 12V power supply was making a clicking sound over and over.
