All, My head
REALLY hurts! Please, I need some help in sorting out wiring!!!!!
I am currently working rewiring my batteries, as well as adding a small solar
panel and a battery monitor
. I wanted to bounce a few things off people.
Generally speaking, I have a VERY simple system. But the setup right now is not...totally safe..... plus, the batteries have been wired to a 1-2-All
selector, which I don't need. Since there is no starter battery
(manual pull start on outboard) I want to combine the batteries to help prolong their life (always drawing from the pair, rather than potential deep hits to one or the other if someone mistakenly leaves the selector to "1" or "2".
To make this more simple, I will put all of my key components into a list:
- ProSport 12 AC battery charger (1st generation)
- 2 Group 27 Deep Cycle Batts (210Ah total), soon to be wired in parallel
- Victron BMV 600 battery monitor
- One 30 Watt solar panel
- One Genasun GV4 MPPT controller for the solar
- 6A trickle charge to batts comes in from the outboard
There is no starter battery, no genset and no inverter
. My whole AC system entails two GFCI wall plugs....one of which I use to power the ProSport 12 charger
I came across MaineSail's AWESOME how-to pages that have many of these same devices...and he cleared up a ton of confusion, but I still feel a little hesitant on a few points.
I have attached a wiring
diagram for the main components described above. This is my guess at how things should look. Note - the diagram is INCOMPLETE...I am missing a host of devices that tap into the DC system, but the basics are there...items that need power at all times, items that feed power back in, and connections to the AC. Once I have the principles worked out, the rest of the connections to devices should be easy.
My questions are as follows:
1. The ProSport 12 charger has two sets of output charging
wires. Once I make the described change to parallel batteries, do I have to cap off one set of the charging
wires? My theory is yes, since hooking the two pos. and two neg. charging wires to the batts would now lead to a short in the charger??
2. Have I set the connections for the bilge pump
and solar panel correctly to allow the battery monitor
to see them, while ensuring power at all times?
3. The outboard
trickle charger really stumps me. Does the diagram look right for where it should feed in? (I believe the line is fused near the outboard)
4. For power that is feeding back into the batteries (outboard, solar and AC charger) does it matter which battery they tap onto?
5. Lastly, can a 1-2-All-Off switch be made into a simple On-Off switch by simply leaving off connections to one of the terminals on its back? It would be nice if I didn't have to buy a new switch...
Any help you might be able to provide would be GREATLY appreciated.
