Woah, hold on there. If you wire the outputs of two MPPTs in series, they will fry! Reason being is a typical buck converter's neg output is shorted with its neg input. It's just a fundamental part of the design. Tying the neg output of one with the positive of the other is the same as shorting...

I cannot vouch for the reliability of any particular converter. I see what you are saying about the efficiency though. Your application is rather unique, and I think this is the point where I would start building my own device to fit the need. I have not seen anyone else using low voltage solar...

I have seen a good few DIY MPPTs. Most are more simplistic and less powerful than what my breadboard prototype is now. I would be interested to see what tracking algorithm others are using. I get great power output from mine when controlled manually, but my P&O MPPT tracking algorithm is...

Correct me if i'm wrong, but it sounds like you are using a 400W set of panels to charge a 90v battery pack for an EV? The main reason there are no 90V MPPTs is because most of them (including my design) use a "buck" topology, where the output voltage must be less than the input voltage. It is...

Hello, I'm an electrical engineer and I got involved in a project requiring a solar battery charger. I surprised to find how expensive MPPT chargers are, especially the american versions "Morning Star, BlueSky, etc.". Why would I spend $100 or more on an MPPT that gives me a 30% efficiency...

Hey guys, i'm a new member, but Ive been cruising this forum for years. It's good to finally be part of such a brilliant community of engineering hobbyists! I need to make a LiFePo4 pack with the highest voltage and power output for the lowest cost. I put together a 16s 1p pack from 10Ah...
