question

The GX model only has one VE.Direct port allowing one MPPT. VE.Direct to USB dongles can provide the additional connections via an expansion USB hub. Worth reading up on this as the hubs can prove to be problematic sometimes and typically has to be powered versions. VE.Can MPPTs won't be an option on the GX model, so also something to take into account. The Cerbo will allow 3 x VE.Direct MPPTs connections as well as offer the VE.Can option and many other features if you were ever to explore them. Either will work regardless.

Hi, thanks for the info , i prefer seperate products incase one fails, i am looking at the multiplus 48/3000, and the pylontech up5000, currently i have 4*400w perlight panels these are the panel specs below, and 3*215 victrons, on 3 seperate victron 100/50 mppt and a pheonix smart 24/3000 inverter. can i use th emultiplus off grid?

The 400s are south east facing so can get at least 5hrs of sun here in derbyshire uk, also the 3*215 victrons are south facing and can pickup pv from 13.00 to 1800 even on a spring day like today, so long as we get some sun. Even in spring my pv is enough to power my (off grid ) home office and tv etc, also occasional use of kettle toasters and air fryers microwave etc and if weve had a reasonable day if possible i can charge my delta 2 and extra battery. The problem i have is that I get so much solar input the mppts stop charging at about 13.00 and i cant expand my 2s2p battery bank.

So i either run 2 systems, one for the small loads and one for the larger loads or i get a bigger battery bank. my batteries are life lifep04, i have 2 spares so a second smaller inverter that might be an option.

i have a south facing garden but the roof is east / west facing so ive got the panels on my summer house.

i assume i wont have an issue charging the 4.8kw battery apart from in darkest winter
