I purchased this solar panel charger to manage power needs for two 200-watt solar panels on my farm. The setup powers a camera system and a mini PC, which is a crucial setup for remote management. The charger performs exceptionally well, and I've been using a phone app to monitor power voltage, charging, and usage effortlessly.This system has made management a breeze, especially since it's connected via cellular Wi-Fi, which handles data without consuming excessive bandwidth. I've had this system running for six months now without a single outage, underscoring its reliability and efficiency.If you're looking for a robust and user-friendly solar panel charger for off-grid applications, this product is a fantastic choice. Highly recommended for anyone needing a dependable power solution in remote locations!

I have this MPPT paired up with two 100w flexible solar panels that have been living in storage for a couple years. The MPPT can be monitored on my phone via Bluetooth, and the unit itself is a piece of cake to get set up. The ratings for my panels put them at the very top edge of the rated specs for the 15A MPPT, but the flexible panels are not quiet as efficient as the manufactures wants you to believe. Paired with a 100Ah LiFePO4 battery, I have seen 12A going into the battery. For a standby, use when needed system, this MPPT will be perfect.

Go through the multiple step wifi setup and the connection works briefly and then disconnects. Redo numerous times with the same results. Tried with 3 different STRONG WiFi services

The device works good. The mechanical quality is very good. Works with WiFi cloud or local, no Bluetooth. Switching from local WiFi to local is not straightforward. The settings are standard for controllers. The software is not perfect but works Ok, the statistics also could be better. Sometimes there are delays of reading current unit data from the cloud.The verdict - affordable controller with connectivity through cloud.

So, this charger worked out of the box. Can't complain about that. The only gripe I have is with the app. I use it to control on/off functionality to the load. It shows the info about the battery and it works (over wifi) on command. The app is very simple, but not the most responsive. The biggest gripe is the lack of scheduling control (there is no option to schedule the on or off of the load), so you have to turn it on/off by hand on the app instead of setting and forgetting.

Il primo l'ho preso circa 3 mesi fà e funziona perfettamente,il secondo circa 1 mese fà e messo fisso a caricare sotto i 48 volt,anche questo fà il suo dovere,oggi ordinato un terzo da mettere nella linea a 24 volt e spero sia della stessa buona qualità.Di negativo non ho riscontrato ancora nulla,anche senza guardare istruzioni l'uso e facilmente intuitivo e facile da impostare.

Il regolatore di carica si presenta molto ben costruito e, almeno in apparenza, sembra solido. Il montaggio è stato molto semplice ed è subito risultato funzionante. L'unica pecca è il manuale di istruzioni che non viene fornito in lingua italiana ma solo in inglese.

sono un tecnico elettronico , prima di montarlo in un camper da un mio cliente l' ho testato per ben due 2 giorni con un pannello di tipo abitazione, e ha dato buoni risultati. l' ho controllato anche internamente , direi buono , l unica cosa fate attenzione a non invertire la polarità
