Hi Everyone, I am hoping you might be able to help. I am having a 60ft semi-trad josher built for initial use as a leisure boat but with a view to being a 5day a week live aboard within a year of splashing her. I am a bit of a geek and really like the remote monitoring capabilities of the Victron kit via the Cerbo GX but am really not sure whether the following is the full electrical supply and distribution spec or if I have missed anything? I am also thoroughly confused at to whether a travel power unit is entirely necessary given I will have dual alternators on the Beta 50 including a 175amp domestic alternator as well as a starter battery alternator. I really would appreciate a quick review of the following or if someone is electriclly minded a wiring diagram???: Beta marine 50 with dual alternator and remote oil filter as extra (+ other adaptions we discussed) 3.5 KVA travel power (unsure if this is required given the spec below would appreciate some advice) 4 x Victron Lithium LiFePO4 12V - 100Ah battery with Bluetooth 3 x Victron Smart Battery Sense - 10 Meter Range 1 x 12v load dump battery (lead acid) 1x 12v starter battery (lead acid) 1 or 2 bow batteries for bow thruster (lead acid) Victron smartshunt Victron Lynx Distributor x 1 Victron Lynx Power In x 2 Bluesea isolator main switches 3 x Vicron VE.Can resistive tank sender adapter (1x blackwater, 1x fuel, 1x water tank) Victron Multiplus Inverter Charger 12/3000/120-50 Victron Cerbo GX Victron GX Touch 50 screen Victon dc-dc convertor (unsure if required or sizing. If installed is a dump load battery required?)

Hi All, I added around 500w of solar to the roof at the beginning of the year, and though it seems to be working just fine I have a couple of ideas that may improve things. Firstly is the connection of the MPPT into the batteries. i have a fairly cheap 40a mppt, standard amazon chinese job, it seems to work well in isolation, however when i start the generator (no shore power) to charge via my 1500w Invertek inverter/charger (stirling rebranded) the mppt display shows a huge reduction in charge current, I'm guessing because the control circuits in the mppt see the terminal voltage as quite high as it is being artificially boosted by the charge voltage from the inverter and believe the batteries to be "full" and thus reduce the solar current? I'm looking at reconfiguring the system to take the most advanting of the solar and have a couple of direct questions!! Firstly, My Invertek inverter does have provision for solar input, it lists several compatible MPPT's which unsurprisingly are all Invertek branded and stupidly expensive. Is it necessary to specifically use an invertek mppt, is there any data communication between the inverter and the mppt which would make it brand unique? If it is compatible, would it be a better place to connect it than directly to the battery terminals in parallel to the inverters connection. Secondly, there are three pairs of terminals on the MPPT, obviously panel input and battery output, the other pair are marked "load" I have left this disconnected as most of my pre-distribution cable is 95mm2 and the terminal struggles with 6mm2 Do I need to find a "dummy load" or something to connect to this? Thirdly, can the assembled think of a better way of doing all of it??? Thanks in advance, Bex
