Hi all, I'm new here and looking for some answers....
I'm currently using 2 solar sets for my house truck.
The first set is my household set, currently one pv combination (3x monocristal 210Wp parallel connected) which is connected to mppt 100-50 also with 4 new agm batteries 24v parallel 145Ah each battery. I have victron inverter 24v500W and all guarded by my BMV (with apps for bmv,mppt 2x, and inverter) also I connected directly to the batteries a cheap nonsinus inverter (chinese) of 1500W (i have 230VAC fridge 150W which needed some more peakpower).
My second set is a seperate victron set for my lead - start batteries. 2 panels with 75-15 victron mppt loading start batteries ( they only use drop load, since batteries stays almost full.. its a bit overdone, but want always to be able to drive when needed).
When turned one the generator/AC from the net, I use a victron centaur 30A 24v to charge my household batteries and a 10A 24v mastervolt charger to charge start batteries.
I'm here at this forum because I want to figure out how its possible to use 2 or 3 DIFFERENT sets of pv (perhaps connected to a new easysolar 24v 1600VA, co combine all the seperate parts into one. BUT, the 2nd and 3rd PV set will be another type of panel with different mppt point and Wp..
So my first question is to figure out, how to use max. capacity of solar panels in different sets, connected to a MPPT, or easySolar. My dream solution is to use 3 different pv sets,connected to a Easysolar, which load both household set and (dropload) my startbattery. I want to ask you guys if this would work and if that means that my victron centaur, my existing mppt 100-50 and my mppt 75-15 become obsolete.
What I already found out here is that each input on the easy solar is protected 30A. But what happens between the 30A connections and the mppt? are the cables just connected together in 1 PV connection at the internal mppt from the easysolar and does this give space for different pv sets?
And second question, is it harmfull that i put a second nonsinus inverter directly to my batteries? The batteries are almost new (bought last summer) and i don't want to destroy them. but i realise with almost no sun, the batteries run empty in 2 days.. which is too fast..
i hope my question is a bit clear and hope to find some tips and tricks to tackle this problem!
thanks already! Ropski. :)
