    UK 3 phase inverter welder from Split Phase / Bi Phase supply 480v

    Hello all, I have discussed my power install before as i am sure a lot of you will remember as it is quite different to a normal setup. I have a split phase / Bi Phase system, 2 phases coming into the workshop from a center tapped transformer. 240v phase to neutral and 480 phase to phase. I have...

    Can't setup generator in close proximity to service panel.

    How many feet can 10-gauge Romex run (inlet box to service panel) and still properly support 30-amp inverter generator? Do I also take into account the 25-ft of 30-amp wire (3-pronged locking) that connects the generator to the inlet box?

    Inverter waiting but plenty of voltage so what is missing

    I have 2 arrays on 2 SMA inverters. One is 500v single string and the other is paralleled 2 x 300v strings. I have just lost one of my arrays via SMA 2500. It is lit but no power generation. I replaced with spare Steca which would not work as it needs more PV voltage so I had to swop over the...

    UK MCBs for Inverter-Supplied System

    My house is off-grid and supplied from an inverter. Max power output of the inverter is about 6kW (25A). Max fault current is 100A. The highest rated Type B MCB that can be tripped by this max fault current is 16A, so I cannot use MCBs with higher ratings than that. I cannot have a circuit with...

    Just a quick one before taking the inverter back. Recently we got an 12v to 230v inverter but started getting a shock off the casing. Tested it and around 80v but sometimes up to 120v. Is there something that can be done or is the inverter faulty
