Re: Connect solar to Blue Sea system combiner

The standby draw is 0.015 amps so a super cheap auto start battery with a 60Ah capacity would take just over 6 months to discharge. A cheap deep cycle with 100ah capacity would take over 9 months and so on. If the switch is used for winter storage best practice is still to completely disconnect the...

Re: Connect solar to Blue Sea system combiner

OK, it's starting to become clear, thanks for that detailed explanation. Just to clarify the switch, it is only there to stop the ACR's minuscule power consumption during storage. It draws a very small amount of current that could drain the batteries over a few months. I think for my needs, I'm hap...

Re: Hot water heater

If you install propane in a boat - as fare as I know - the bottles stay outside. Then you will mount a switch INSIDE the boat that can turn the gas off OUTSIDE the boat. So there would be just gas on in the boat when cooking. That was the theorie... So forgetting to switch of the gas... will happen...

Re: Connect solar to Blue Sea system combiner

I'll add that the blue seas installation diagram shows connecting the terminal to either the starter or alternator. It is also quite common to run the positive charging cable from the alternator to the starting lug on the starter which runs back to the switch...not an ideal setup but just clarifying...

Re: Connect solar to Blue Sea system combiner

. This: https://www.bluesea.com/products/8686/Dual_Battery_Bank_Management_Panel keeps the two banks completely separate from each other, so no voltage drop on sensitive electronics (plus the added bonus of 24 hour fuse protected circuits); Ok Yeah :P that's a cool device - Based on what I read in ...

Re: Connect solar to Blue Sea system combiner

The thing you guys have been posting about is the batteries being all connected during alternator charging. That is an issue. That is an issue but not the one I have been discussing. B2B or DC/DC is what should be installed when mixing battery chemistry, voltage etc. With same battery type and a VS...

Re: Connect solar to Blue Sea system combiner

Regarding the long term storage switch: ” 9- “An ACR will allow the start battery to drain into the house battery and leave it depleted.” = FALSE This statement takes us directly to Myth & Lore #9 “An ACR will allow the start battery to drain into the house battery and leave it depleted.” The fully...

Re: Hot water heater

Propane is allowed inside boats and there are ABYC standards for it. While a continuous propane leak into your bilge can end in disaster, small leaks do dissipate rather quickly. I do like the idea for deck showering though.

Nice job boat. Marine install on a camper van should last 100 years.

Re: Connect solar to Blue Sea system combiner

See the article I submitted earlier for Starscream, I don’t think he read the whole thing, it is long. https://marinehowto.com/automatic-charging-relays/ Read ALL the way down through multiple titles. Here is the schematic you want if installing and ARC/VSR (you can change out the 3 selector switche...

Re: Connect solar to Blue Sea system combiner

When charging with the engine the arc will have to stay open until the house bank is charged flowing through the start battery which causes it to cycle sort of (more depending on the discharge of the house bank) which can shorten the battery life, more so if a regular auto start battery. The whole p...

Re: Connect solar to Blue Sea system combiner

Starscream see below link for ARC's. I think Maine goes into DC/DC as well. DC/DC (look up Balmar digital Duo for an example) They allow for a more precise relay between banks, also allows for mixed battery chemistry ( FLA house banks and an AGM start for instance) https://marinehowto.com/automatic-...

Re: Connect solar to Blue Sea system combiner

I like starscreams setup but would route the engine alt to the house bank as well. Problems can arise where solar and alt charging with the ARC simultaneously or worse running a dc/dc. Problem routing through the battery selector switch is when engine charging and someone cycles the switch to ‘off’,...

Re: Engine not starting – Ground Fault?

You really should wire the engine directly to the house bank and a VRC/ARC between the house and the start battery. This way you wont cook your rectifier again (that happened when you switched your Perko to 'off' with the engine running). That way the engine's charging system will always see a batte...
