    2 x MPP PIP Max 2x11kw output voltage issue

    Hi Irmscher001, I've just bought 2 x MPP Max 11kw inverters and 10.44kw of PV. 30kw of batteries arrives in 6 weeks. Looks like my setup is almost the same as yours. I think I may have found something that could explain it? On page 40 of the tiny manual you get with the inverters there is a...

    JA Solar Panel Module Grounding Restriction with MPP Solar Non-Isolated Inverters

    Hi AntronX, #4 - 4/0 - this is AWG yes? and equates to 21.1506 sq mm. csa.? Sorry, I'm not that familiar with AWG. In the U.K. it's all sq.mm. The main earth connection (Ground) at the grid entrance point is 16.0mm squared at my property. Live and Neutral conductors are 25.00mm squared - 240v...

    JA Solar Panel Module Grounding Restriction with MPP Solar Non-Isolated Inverters

    Yes, this topic does seem prolific. That's what I found confusing. Now! the question of neutral earth bonding and the TNS system used by the grid in the U.K. That also causes much confusion. Maybe another day when my system is installed. :)

    JA Solar Panel Module Grounding Restriction with MPP Solar Non-Isolated Inverters

    This is easy for me to do as the main support posts for the unistrut frames are to be timber (not installed yet). Also, it provides adherence to NEC rules to ground back to a single point. However, what AntronX is interesting as what is the case if the supports were steel? The whole PV panel...

    JA Solar Panel Module Grounding Restriction with MPP Solar Non-Isolated Inverters

    Totally agree. These JA panels new are just £82.00 GBP each for 435w, bifacial, all black panels. High PID degradation seems to be much lower on recently manufactured PV panels. The cost to replace all the panels in say, five years wouldn't be a lot and probably would be a benefit as much higher...

    JA Solar Panel Module Grounding Restriction with MPP Solar Non-Isolated Inverters

    Hi Zwy, Thanks for that. The manual I have is Version 1.3 Oct 18th, 2019 so, five years on now and a lot has definitely changed. I should have checked that! As Hedges says, most panels these days are resistant to PID so I guess the current panels I'm looking at have greatly improved in this...

    JA Solar Panel Module Grounding Restriction with MPP Solar Non-Isolated Inverters

    This is my first post to a forum so please excuse any errors. I have just ordered two MPP Solar PIP Max 11kw Inverters and was planning to use these with 24 x JA Solar JAM54D41-435/LB Mono N-Type bi-facial panels. However, upon reading the installation manual for JA panels they say that their...
