I’ve got the email with the firmware from the local seller, sofar didn’t respond directly to my email. Anyway system is working fine, I’ve added a new row of cells, now a total of 840 cells in 14s60, self usage has now increased from 25% to 60% with just a few days of sun. I’ll have to add more...

Yes, I have 2 inverters both on grid and are 30m away in the back yard, that is why I measure AC production on the main cable from PV.

I found the problem :) clamp should be only on the line wire, initially null and ground was in the clamp… my mistake I didn’t read very carefully diagram from Sofar

Hi, seems problem with CT continues, now I've changed to use eth cat.5 separate cable for each CT as you mention above but seems still signal is influenced between the wires, so other should be the cause of the problem. Did you remove the insulation from the cable with 3 wire (grid and...

Hi, I've changed cable to awg12 - 2x0.5 with extra isolation layer, seems to detect now different values, but are very low values compared to the smart meter reading. 0.06kw production on me3000sp vs 2250w reported by smart metter. I think I'll change to eth cat.5 cable to see the results...

For now I have all parts connected and 14s40p working, thanks for the tip. One more settings mismatch is that jbd BMS has his own settings for protection, so a few times inverter shutdown because jbd protection. I've put 15amps max charge/discharge for now to make it working with the grid. Other...

Hi, did you finish your power wall? I just connected inverter and seems need to communicate with bms that is no from phylontech, how did you solve the problem?

And now the power on... fault, seems inverter need to comunicate with the bms that is a no brand.

Hi Hi, how did you solve the connection to BMS, I have fault error ID52 on ME3000SP?

Glade to see youwill usethe same inverter. Just a quick question, do you think copper wire from Cat5 ethernet cable will be ok to weld on -ve?

Hello everyone, I didn't expect to get so many replies :). Thank you for feedback! You all are right,I'll lower the fuse to 20-25Amps with 14s40p, as I add more cells 14x20 or 14x10 I'll change the fuse, so keep maximum 10-12A for each14x20 cells. On inverter specs I found asettings to limit...

I've started building a new power wall 14s20p as proof of concept and then plan is toexpand it to 14s40p/14s60p. PV array contains 22 Canadian Solar 285W, Sunny Boy 5000 on grid inverter, ~5 kw installed power. My plan is to use Sofar ME3000SP, so nothing will be changed on existing grid, just...
