Looks like they both sold very quickly

Ok can see a few more of these advertised at 31 and 38 volts when they should be 105 I think. If two are faulty is it possible that I could maybe make one good if the cells are arranged a particular way?

no takers? @Travis_signaturesolar what do you have in your system in terms of breakers in the series/strings to make safe for any work you need to do?

Hey all Still in the investigation phase but already have a solax charger that does 70-360v battery so looking at Valence for the battery. I know I will need a u-bms programmed for whatever configuration I end up with (the more the merrier) as well as a dc isolator and various other things but...

Really wish I could find the u27-36xpd for £90 each at the moment. :-)

Meant to say 12v is 136ah 24 are ?? And.the 36v are 50. Either way they are all roughly 1.7kWh

P30-36C are 36v X 30ah so not same capacity as the 12/24/36v u27's which are closer to 50ah so £140 per kWh

It's going to be the higher one

It's a reading taken at the Y plug

Have an opportunity to purchase an X1 charger with bms and one 4.5kWh battery but the battery reads just 30volts. Can they be recovered from this low or is it dead for good?

can you check your export setting on the SOLAX X3 HYBRID see if it says 1000 if so drop to 0

never mind I can se you have posted in that thread as well :D

I have just started my discovery journey with Valence stuff for home battery storage and this thread has been helpful for the XP series https://diysolarforum.com/threads/valence-xp-super-thread.5683/ there is a link in there for both the 12.12 version and also the older 12.9 think the cable to...

So further digging and Eaton UPS stuff seems to have some 72v architecture but if utilising a UPS which is effectively a charger inverter how do you modify it to provide power based on draw and solar cycle? I know turning the power off to the input is going to make the UPS kick in and supply...

I tried searching for 72v and 110v (108) but again nothing like an inverter/charger for 48v.
