Solar Controllers--Don't be a Sucker! :(
Just got to say it again, how it is we are sitting here for five months off grid on solar with no problems at all (third season on solar like this), using the non-programmable, non-MPPT, solar control...

Wow, that's getting the most with a TC for sure.
BTW, how do you run the air conditioner (how big is it)--how much starting draw (voltage drop on that on the 300AH bank?-how much running draw?)
Several threads/posts about how you can't run the air conditioner off-grid except with the big gen or a smaller gen with inverter assist just for the start and recycle part. So you are doing it with no gen at all. How?
Ok my rant was that you can do it all with just cheap PWM. So just to fight my corner, not saying everyone is a sucker, please explain:
You have 2-100w and two 64w arranged in two arrays (at times anyway)with two controllers. That is 328w and two $250 controllers (price they are here approx.) for $500 of controllers
I have one 130w and 2-100w panels with two $39 controllers for 330w in two arrays, with $78 of controllers
The rant is about:- what can you do that I can't for $500 vs $78 ?
(Never mind the data logging and all that, which is a hobby, not charging batteries and running loads :) )
