Great item! I have a solar panel on the roof of my RV and this item work great!
I purchased the 20AMP Renogy version with the bluetooth module. My ONLY problem with the module or in this case really its design is that the signal strength does not penetrate walls well.. so to be any real use (the 25-meter distance supported).. really is not lived up to. My window to outside mounted BT-1 might be 25feet max away, but it still has problems syncing up .. and normally I have to move to a room that has a window that is 10feet from the BT-1 .. rather exasperating . OTHERWISE the 'older' app connects and work pretty well .. thought still a bit archaic as apps go. I will give them great credit as I am using a tablet .. versus a cellphone .. and my tablet is NOT supported by the newest app.. so.. I guess I get what i deserve.. :-)
Great buy!!! Super fast shipping!!!
The product is working very well. It was difficult to select the battery type because the print on the screen is so small. Also, the directions were not clear regarding setting the load parameters. It took some trial and error to get it right.
good product.good product.good product.good product.
This has been running on my camper for over a month with a 230W solar panel. Keeps battery charged without overcharging. When I killed the battery overnight (<6V in the morning) it brought the battery back to life the next day, no issues. I specifically got this model since I plan on switching to Lithium batteries eventually and this controller will handle that transition with a few button pushes. Installation and setup was easy.
This is the best energy product equipment I have ever used.
Works like advertized & the cell phone connection is great.
It’s been 4 almost 5 months since Iv installed the unit on my truck. It’s been doing great charging 116ah of LTO. I bought the unit with the Bluetooth module but the Bluetooth has died on me. Iv unplugged it a few times. Power cycled the unit. It never came back. The charger it’s self is fantastic. I use it at shows to keep the alternator from melting down trying to support 27,000 watts. I can just shut down the truck and we’re all good. Keeps charging. Currently planning on getting 3-4 units for the camp to Keep all the vehicles out there topped off
