I'd like to get a weigh in from the group on something. A buddy here and I were discussing his tiny house and he said he'll use a mini split for air conditioning but he will use electric oil immersion heaters in the winter. I advised him to use the mini split because the electric resistance heater is only 100% efficient but COP on heat pump is 3:1 or 5:1 depending on outside temperature.
What say the group?

Hey I got a local guy who bought the wrong victron Multiplus II unit and would like to sell it. Never been in service. 3.5kw, 120voutput, 48v battery unit. Wants $1000 OBO. Perfect unit for an RV. Can be stacked with another 3.5kw unit.
My friend's problem is that you can't mix and match these units and he has two additional 5kw units that he cannot use with this one... so he will replace this unit with another 5kw unit.

Its been a few months coming but I have finally finished my "poor man's victron knock off buss bar". Wife didn't like the exposed bus bars I had in the original system so I found 8mm x 30mm tin plated bar stock on line and bought a meter of it. I routered out slots using a jig in some PVC board to hold them. And finally made a plexiglass cover for them.
Of note, the battery cables are intentionally run left to right on the top bar and right to left on the bottom bar. That makes the algebraic sum on the distance to the shunt the same for all batteries.

Kudos where they are due... For 48v MPPT battery chargers I use Morningstar Tristar 600v 3kw chargers. They are expensive. But tech support is off the chain. I wrote code to read the voltage and amps every 15 seconds from them, but now would like to be able to remotely command them to charge at varying amps depending on how much power my entire system is exporting. If my exporting is <20kw, then I want to command these things to run as hard as they can.
So their tech support guy wrote me back at 10pm last night with all the info I needed. wow.
