So since my first installation in spring of 2022 with 3 pcs. Growatt SPF-5000 ES and premade batteries with 35mm2 DC cables the system has been enlarged in several steps. This is a 3-phase setup. Firstly as the Growatts (5kw each) started taking each other out with fires and literal explosions...

The last few days the server is lagging heavily for me. When I click on threads it sometimes times out with an error message. If I then click on the Reload button on the bottom of that error message from your backend the page loads normally. Sometimes the pages load normally but with a delay...

07.10.2023: Started snowing for the first time this fall in my old home country of Norway. Winter is truly coming. I know I cringe when I think of my panels etc. seeing the snow ^^ ... Are you prepared?

Due to wanting to eliminate local grid noise and instability (incl. very variable volt level) I do not want my grid connected through the inverters all the time. I need to ensure a 230V stable net in my house at all times, also due to a sizeable amount of IT equipment and audio gear. Which...

Looking for a busbar for my new DIY batteries to tie them into my existing battery bank. A lot of the simpler versions out there is everything from stainless steel to brass etc. Not optimal. Victron has 2 different types (I got no Victron equipment from before) Victron Lynx Distributor and the...

I will be adding a double DIY LifePO4 battery with 15S and using 2 pcs. JK-B2A24S20P BMS. Couple of weeks until the BMSs is here (ordered one more as backup...) Bought cells through Qishou - EU warehouse delivery. Planning to use EVE 280K, 30 pcs. 2 banks of 15S. This is to be an extension to...

I am running my 4 big batteries with Voltage settings only as the BMS don't communicate to the Deye (Sol Ark) inverters I'm using. The MFG does not list any voltages except 48V nominal (this is a 15S2P config) and charge and float voltages (I am running 54V and 52V at the moment). What is YOUR...

Funny story...NOT. After being in production since mid june...my 3-phase 3 Growatt SPF 5000 ES inverters had a huge fault the other day. Woke up from a nap some hours later - Darkness old friend ^^ :) Ran down to the my tech room. Got an overload message on one inverter. Code 07 - Overload...

Got my strings in series, 9xLongi 72cells single sided 540w panels, only one string for each inverter (3-phase). Voc STC 49,50 - NOCT 46,54 Short Circuit Current lsc/A is STC 13,85 - NOCT 11,20 Current at max power Imp/A is STC 12,97 - NOCT 10,43 During summer I see max. 405V. Growatt SPF 5000...

One of my Longi 540w/72 is emitting a buzzing noise in sunlight mid day, detectable from 10m away. All others seem to be silent. Sign of a faulty panel? I have the correct volts/watts from that 9-piece array. I have 4 spares, should I swap it? These are also newly delivered so I have warranty...
