Review on 🌞 NOYITO MPPT 5A Solar Charging Board - Efficient 1-100W 9-28V Charging with Reverse Connection & Anti-backflow Protection - Low Power Consumption by Joshua Gallegos

With such a dangerous device, the instructions should at least be understandable. The person who wrote this manual was neither technically nor linguistically savvy. There's a slightly better version of the guide that can be found online, but it's also vaguely wrong. (Maximum *strong* point tracking, not maximum "current" point tracking. Check out the graphs.) You can play around with this until you get the hang of it, but it's really not worth the time or the risk. Do not buy.
