That's my feeling. And I have yet to see anyone explain how an MPPT would be better if you design a system from the ground up-matching all components.

I found this thread interesting although it is a little old. I put my first and only solar system together using 280ah cells, Electrodacus SBMS0, and two DSSR20s. Connected to four used 235w, 60 cell panels. It's a 24v system. Work great but never had another system with MPPT and etc. Always...

Yes, that is what I meant(bad wording on my part). I don't actually refer to panels as 12v or 24v, but yes, 60 cell panels for a 24v system. You still haven't convinced me that if I'm using 60 cell panels with DSSR20 that MPPT is better. Trying to learn-I'm not an electrical engineer by any...

yes, that is true. that is a down fall of DSSR20. You must match panels to voltage of your system, but since good used panels are dirt cheap

https://diysolarforum.com/members/sunshine_eggo.39831/ Are you saying DSSR20 is a PWM controller?

I've been using Electrodacus for about three years now with DSSR20s in my camper. I love it! No worries of what size bms to use, no need for sizing charge controller or paying for expensive charge controller. Only thing that I don't care for is having to use 60 cell solar panels only-I have a...

I just purchased a ‎WZRELB 3000w 24v inverter to replace my Xijia inverter in my camper van. Xijia worked great for about 3 years. Used every day for three months straight on a summer road trip. I was preparing for another trip and turned the solar system back on. I noticed that I could not turn...

I have been looking at myself. Wondering if any different than something you can buy on ebay, amazon, alibaba? One thing that I don't like is only has one year warranty.

That's what I got to thinking. I would then enclose two shunts in plastic electrical box??? I also heard that wire going from battery positive to battery charge shunt should be very short and image quite over sized

Question/concern: From the positive battery terminal through shunt and disconnect switch/busbar, there is no fuse protecting this wire/shunt/disconnect switch/busbar. This is how you're suppose to wire Electrodacus. Do I have a concern or is there a way to protect this run?

On the electrodacus system the shunt goes on positive side and their is usually two shunts-a battery current shunt and a pv current shunt https://electrodacus.com/SBMS0/SBMS0v03d.pdf

I finally completed my mobile solar system using Electrodacus SBMS0 and DSSR20. Everything is working well! It is a 280ah 24v system. As I look at system something strikes me (I'm a newbie-not an electrician, engineer, etc). First let me explain how battery is connect. Positive wire (2/0 about...
