POWOXISolar Panels Charge Controller, 8A Battery Regulator for 12V Solar Battery Charger, Solar Battery Maintainer and 12 Volt Batteries Power Kit Safe Protection

Great product as says on description

Bought as a controller for a solar charger for the cab battery in my motorhome while in storage.Only 0.8A trickle charge, but its enough to keep it topped up between uses.

Useful to show correct polarity and charging situation. My solar charger needed the supplied connectors to reverse the lead polaeities which was why my charger was not working before (didn't know that!). Took 1 star away as the device leds are not very visible especially in bright sun light.

Bought to replace older regulator that suffered from an ingress of rainwater.This regulator is slightly more sophisticated having indicator lights for connection, charging and battery full.

A waste of money. The instructions that came with the device contradict those printed on it. The order of making the connections was reversed between the two sets of instructions. The instructions on the device spoke of green and amber lights when there are two red lights. The output voltage (without a load) to charge the battery was 8 volts although the input from the panel (without a load) was about 18. So no charge was made to the battery.I would like my money refunded, but as I had to cut the connectors to fit my installation I don't imagine it can be returned.

It's ideal I've connected it to my electric motor bike auxiliary battery and it just keeps the battery topped upMany thanks

This is actually the second charge regulator I've had, replacing an identical earlier one. Although the brand name on it has changed, the product is the same. The earlier one (branded "POWOXI") actually worked well until I made the mistake of leaving it out overnight in my car - see below.....First thing to remember is that this is a cheap product, and cheaply-made. The (Chinese) manufacturer warns that it cannot be mounted outdoors, because the casing and internal circuitry can't survive constantly changing temperatures - this was the reason my original controller failed, because I thought it could be left overnight under the bonnet lid of my car.The connectors are SAE-type twins, and also cheaply made - the plug's female section can fail to make contact with the male, and I have had the male section fracture before. I suspect the same is happening again with this replacement controller, so will have to improvise to make the connections tighter.So far, this replacement controller has failed to show any life, so I don't know whether it is faulty or whether the solar panel I have is now at fault. Currently I am not getting any response during overcast/cloudy daylight conditions. When I tried the panel on the one sunny day we've had this winter (2020/21), there was still no response from the charge controller - no lights, nothing.Jury still out, I think. Maybe things might improve as we go into Spring and the daylight hours lengthen.JUNE 2022 UPDATE: the problem is solved. It turns out that the SAE connector was wired the wrong way round!! Once this was corrected, the regulator came to life and is now registering a charge from my 20w solar panel. Not only that, but it's been hanging on the shed exterior wall for a while now and has survived a number of showers apparently unaffected. It even registers a charge on overcast days and until daylight fades. It looks like it will be every bit as useful as my old one was.Reading other reviews it seems that there's been quite a lot of these "wrong polarity" SAE connectors coming out of China. Why this is we can only guess at, but it's a clear indication that quality control isn't high. In some cases it could lead to other equipment being damaged so test these connectors first if you can. They do work, but you must be satisfied that everything is the right way round.

Operates well and does not over charge the battery
