EPEVER MPPT Solar Charge Controller 40A 150V PV Solar Panel Controller Negative Ground W/ MT50 Remote Meter + Temperature Sensor PC Monitoring Cable[Tracer4215BN]

Excellent charge controller for six gauge cable

User setup straight forward, see what is happening at a glance.

This is a good MPPT charger. I can set my own battery parameters using the MT50 monitor.Other off grid folks notice the same problem I used to have with my old chargers...a lot of times my old charger would go in float and shut my solar array off and I would be running things off my battery bank during sunlight hours!!! I have a large battery bank and have set absorb to 3 hours and would have set it for more hours because my batteries can be in absorbtion or boost charge for 12 hrs. I set my float charge up to 14.5 volts. I want my batteries charging as long as the panels can gather energy and I definitely do not want to be running off batteries before it is night time. I could not figure out what my earlier chargers were doing in float but they allowed my batteries to drain a little in afternoon and then kick back into charge mode when a preset low volt level was reached in float mode. This usually occurred right about the time the sun was setting so my batteries would not be at the maximum charge and surface charge as I headed to night time. Check your settings on your charger if you are off grid and your battery bank voltage at night. It took me a summer to figure out was going on and made me mad to find the sun was shining and I was running my home off the batteries instead of the panels!!! I love all my free daytime solar power..crank my freezer up full blast and charge up all my tools, phones, computers, run tools etc. After my batteries are full all the surplus electricity is free!! This Solar Epic has a 20 amp load outlet and shows the battery being charged and the load powered by your panels. Love the Solar Epic and have extra current and panels ( not over 130 volts) hooked to it so the charger is always getting max power to it. You can have more than 40 amps going into it but do not go over 130 volts. READ THE OWNERS MANUAL! UPDATE...unit is working great!!! The tracking seems to react quickly to passing clouds etc that some reviewers had complained was slow. I may buy another unit in the future. UPDATE.. I bought another of these Solar Epic chargers and added more panels. I have the MT52 remote for lithium batteries now and put MT52 remotes on both chargers. I have ten panels on each charger but keep the voltage way below the max of 150 volts...the excess amps are handled by the charger to a max of 40 amps. I also replaced my lead acid batteries with Eve 304 lipo4. Yahoo! I will probably be building bigger. I added a 43" TV and new freezer...off grid life is good with all this new technology and drastically lower price on panels and lithium cells! I already have a panel up with room for a couple more of these Solar Epic chargers. I noticed Will Prowse on YouTube had good things to say about this charger (I hope I am allowed to include this). I have electricity when the power is out!

nice having the monitor to see what's going on with charging at different times of the day month or year, know exactly how much power I'm producing , casing is heavy duty

Knocked off a star because temperature sensor went bad in a few months. Purchased this controller in April based on reviews and came highly recommended by Will Prowse. Three months in the temperature sensor went bad. At 94° it said my battery temp was -1C (30°) and shut down my solar to protect the battery. I contacted the seller and they were quick to respond which was a plus. The problem though is that apparently they have no replacement parts. They messaged they would send a replacement temperature sensor but that it comes from the manufacturer and would take awhile. I don't know what awhile is in actual time and I'm hoping it's before cold weather but will update on seller follow through. The charge controller itself is solid and does its job well. Update New sensor arrived. We're using this controller with 400watts of solar in series and a 300amp hour battery to keep our 12 volt compressor fridge going in triple digit heat. It does the job and it does it really well. Big thank you to the seller for follow through and getting us a new sensor. Added fifth star even though there was an issue because sometimes things just happen and the seller was on the ball and made it right. Would purchase again.
