I'm not an expert in North American electrics, but wouldn't you'd also need to isolate the house from the grid when using the inverter in this way to prevent back feeding current and creating a safety risk to technicians working on the lines?

I'm trying to plan a 48v marine system as well (for AC leisure loads, not propulsion). One thing to consider is how you're powering your 12v loads. In my case it's 24v loads. I'm planning to use a DC-DC charger to step down from 48 -> 24v and then connect this to a smaller 24v battery bank to...

Made it with Google drawings. It's not really the best for this, but it's free

I'm hoping for some review / commentary on my design for the house system on my boat. Parameters The boat is a fully residential dutch barge, lived on 365 days/year. All electric kitchen with 240v domestic appliances (induction cooktop, oven, separate fridge, freezer, combo washer dryer)...

The AC loads are (non exhaustive list/all 240v) Induction cook top - 20A max current - can be programmed to run as low as 10A Oven - 13A max Fridge Freezer Washer/dryer combo DAB water pump Main lighting TV Networking equipment Small appliances Diesel boiler The DC 24v loads are (also non...

I don't, but also the 24v component of the boats systems make up a nominal portion of the overall electric demand. The primary demand is 240v AC

The reason for going to 48v is that I'm effectively looking to build a 32A 240v supply. The boat is all electric and routinely pulls close to that when cooking. There's only one Victron 8000 VA inverter that runs at 24v. 48V brings more choice for inverters at lower cost, easier to build/buy...

Thanks for this. Compelling reasons: The boat is my full time home. Appliances are 240 domestic variety. There's no gas on board so all cooking is electric. Peak load is about 32A. We are normally on 32A shore line, but for cruising we need enough juice to be able to cook, etc. 48v means...

I'm curious why an MPPT solar controller as opposed to a DC/DC converter?

I'm looking to build a 48v system on my barge. Currently all DC loads are 24 volt. I don't expect that alternator charging will be a primary source of power (I have a 7000w generator plus planning for solar). The boat currently has separate 24v alternators for house and starter batteries. I've...

I've been thinking for a while about building an electric system based around 48v batteries. My boat has all electric main appliances, so realistically a 48v system would be best for powering the inverter loads. The existing DC equipment onboard is all 24v. One of the design problems I've got...

Hi all, I've recently come across a type of solar panel which combines a PV collector and thermal collector into one unit https://www.convertenergy.co.uk/pv-t-hybrid-solar Other than some marketing pages, I can't really find much info in terms of vendors, pricing, usage constraints, etc. My...

I saw someone recently who had used a cheap touch screen photo frame "with some small modifications" in place of the victron screen. Not sure what the mods were, but worth looking into

These guys also seem to make 48V alternators in the US. Similar costs: https://www.nationsstarteralternator.com/searchresults.asp?Search=48+VOLT&Submit=Submit

There is a company called Balmar which makes 48v alternators designed for charging lithium batteries. Very expensive. in the £3600 / £4000 mark. I've looked long and hard at how I could charge a 48v bank off a 24v alternator and, at least to date, haven't come up with a good / cost effective...

In the case of the 24/8000 option, the manual states a recommended fuse rating of 500A. In this case of using two connections, should there be a 500A fuse on each, or 250A on each? Guessing 250A to protect the cables?

Apologies if this is a topic already covered. I've tried the FAQ but can't really find anything clear. The manuals for some victron inverters instruct you to use twin cables to connect to the batteries, and have two posts to mount those cables to. I'm looking at either the Quattro 24/8000 or...

Hi there, first time posting so apologies if I'm going over old ground. I'm looking to install a solar thermal system on my liveaboard Dutch barge and was hoping for some thoughts/feedback on my ideas. I've recently had the central heating onboard updated. The primary heat source is a 15 kw...
