EPEVER MPPT 30A Solar Charge Controller 12V 24V Auto, 30 amp Solar Charge Regulator MPPT Automatically Identifying System Voltage, for Lead-Acid Lithium Batteries and Load Timer Setting

Works a treat, had a cheap £10 one on before because I had AGM batteries, switched to this with lifepo and it made a big difference to efficiency, the sun no longer has to be full blast to add charge.Seems like a lot of cash but worth it.

Simple to set up and use.Shame they don't build in connectivity to network.Easily done nowadays.I have mine running 24/7 on a hydroponics system.

Great just what we needed

This is the second one of these chargers that I have owned. I live in a caravan on a building plot that has become hoplessly entangled in bankruptcy & corruption.The net result is that my stay in a caravan for a six month build has turned into 3 years of no Electricity, water or sewage.After a while I started to look at solar power to enable me to live without a generator running 16 hours a day.Through a process of trial and error I have wound up with 3 ex-solar farm panels, 8 100Ah lead acid batteries a Honda 2KvA Generator and this solar charge controller. It is easy to set up and provides good monitoring of both the Solar PV output and the battery state and on bright sunny days provides a steady 40A charge current. It also highlights the weakness of solar power if, like me, you are off grid. From the end of September until the end of April there is simply not enough energy from the solar to keep the batteries charged despite the undoubted efficiency of this controller.The first one of these showed that it really is only splash proof , the electronics were destroyed by water getting in round the LCD display, I had the lid of the box that it is stored in open for a few minutes whilst I checked a connection in a rain storm. It did not stop working completely but became very erratic and it was only when I opened the box up in desperation to find out why it was so erratic that I discovered the water damage.In my installation, this charger, my generator fed mains charger and my inverter all live in a plastic garden storage box with a two 12v computer cooling fans, one at each end of the box to keep the whole installation cool as the solar charger becomes quite hot when running flat out. Ventilation for this unit is essential to keep the operating temperature within acceptable limits. It's hard to know just how much more efficient a MPPT controller is than a cheaper PWM controller in real world situations. Having used PWMs before on a boat I think on balance that it probably worth the extra cost, but is not a game changer in comparison with other elements of a solar setup

Been fitted now for 1 month swapped for a cheap controller, already seeing better changing results from my 100amp solar panel. Good solid device with strong terminals.

I have fitted a few different solar panel set ups before and I have never been impressed with both the quality and performance of the charger controllers. This however is excellent quality and is very easy to use and fit. The performance is excellent and coupled up with 200w of solar panels and the MT50 remote panel is an excellent set up. Our 100Ah battery charges and stays full all the time. I would highly recommend this controller setup.

Use it in our Motorhome as a second unit, this plus a second solar panel. Small, lightweight and a full display, I don’t want yet another app on my phone. Our batteries are AGMs this charger floats off perfectly and my favourite bit, it will tell me “the story so far” ie how much energy it has put in over a set period. Great when the van hasn’t been used and only the security monitors consumption can be shown.

I now have two of these controllersone 40A and one 30A as i have upgraded my panelsand the 40A was running flat out all the time.I find these controllers very good at what they domy input voltage from the pv array is 72 volts and when the panels areproducing 5 amps the charge controller is outputting around 20 - 25 ampsto the batteries. I have had the 40 Amp for around 6 months now and it has workedhard to keep up with my demand but has been faultless in it's operationVERY IMPRESSED
