I'm just finishing up our new solar panel AGM battery system for our remote cabin in Ontario, where we recently found out that the trusty propane-mantle lamps trip the new CO alarm! It turns out we've been breathing too much CO for years by using those lamps! So we switched to solar PV panels to power 10 warm-light 2W LED lamps. Since our battery bank is 24V, I bought a SolarConversions(SC) EQ-12/24-20 which promises to also help balance voltage between the 2 12V AGM 110aH batteries. My question is how to wire in a pair of MidNite Solar circuit breakers.
Following the wiring schematic provided by Solar Converters (SC), I plan to attach the SC common flying lead to the 24V battery bank (-) common using a bus bar. However I plan to install a circuit breaker to the 24V (+) flying lead and the 12V flying lead (which attaches to the jumper between the 12V batteries). When connecting to the 24V (+), I'd like to add a second 10 ga. wire to the (+) side of the breaker that feeds the MPPT controller. It seems like the breaker (+) terminal opens wide enough for a pair of 10 ga wires, but is it bad form to try to connect both at that terminal? Otherwise I can move the wire to a nearby terminal strip where I can distribute 24V (+) power to both breakers. I have the idea that I should try to minimize wiring connections especially for lower power systems, like our 24V cabin.
I don't have a 2-pole circuit breaker for protecting/switching the two power leads of the SC EQ, so I'm going to use two separate breakers. I'll order a 2-pole breaker and replace the separate breakers later in the winter.
Finally, what do you think about the Solar Conversions EQ device? My main use is to provide a 12V output for charging the cellphone and E-reader, however I like the idea that it will help keep my two AGM batteries in balance both during charging and discharging.
We have a small generator in case we don't have enough winter sun to keep up with our anticipated demand of around 400W/day.
