## Questions & Answers

**Q: I am considering this unit for inside an automobile on the dashboard.  Any reason why not to do this?**
A: Husband purchased these for motorhome coach battery.  He has had the solar unit sitting outside our motorhome for five days and it is not producing any readable power to the battery.  He is considering returning the solar panel as it is nonfunctioning.   Goodluck.

**Q: Is the charge controller rated for maintaining and charging agm batteries? and at 20 watts is it about a 20 hour charge time for a 33ah agm battery?**
A: It works for agm,flooded, gel, sla batteries. The 20 watts solar panel generates 1.1A peak current in strong sunshine to trickle charge your battery.

**Q: Green flash and then 5 quick red. Battery it is on is at 11 volts. All brand new. Battery also doesn't have any draw on it**
A: This usually happens when the sunshine is too weak, place the solar charger in strong sunshine and check if the LED indicator back to normal? If problem is still there, pls contact our support team; support@sunerpower.com, will get back to you and make it right.

**Q: Does it store energy, Can i use it to power my IP camera day and night?**
A: No, it was designed to charge battery, don't store any energy.

    Nicer than the Deltran Battery Tender, simple fix to address reversed polarity charging issue
  

*by J***H on Reviewed in the United States on December 31, 2020*

I have purchased this Sunerpower solar powered trickle charger to charge my boat battery off-season without removing the battery and putting it on a battery tender in the garage as I used to. I had been using the Deltran 15w Battery Tender solar trickle charger ($140) until a tree branch fell down and shattered its glass. This unit looked appealing due to the more traditional solar panel mount, which as you can see in my picture is on a tree next to the boat. I like that I can bend the bracket to fit the tree and angle the charger up to the sun.Upon installation, as many other reviewers have commented, the charge light was solid red indicating reversed polarity to the wires. My boat battery is connected with standard SAE connectors and extension cables (red+, black-) and I never had an issue with the Deltran. According to my volt meter, those wires read -12.86V, so it's actually the SAE extension cable reversing the polarity not the Sunerpower unit itself. To fix this there are three options: reverse the leads at the battery so that the red+ is on the negative battery terminal and vise versa; purchase a SAE reverse polarity adapter off Amazon ($6 for two); or use the included cables that come with the Sunerpower unit. As I didn't want the hassle of undoing my winterized boat cover to get to the battery and considering I prefer to use the extension cables exactly as they are, I chose the cheap Amazon adapter (see picture of tree) which arrived in 1 day. Immediately the charger was fast blinking red indicating active charge, and within a day with decent sunlight, the charger turned green indicating a full charge to the boat battery (see picture). What more could I ask for?So buyer do note that this unit is quite simple and nice and hopefully sufficient to charge and maintain a single deep cell battery, and I like the ability to view the charge status underneath which I couldn't do with the Deltran unit. But unless you use the supplied cables, you will most likely need to reverse the polarity on the wires which is a very simple fix. PURCHASE THIS UNIT WITH A SAE REVERSE POLARITY ADAPTER. Happy charging.

    Good Deal for Standby Power
  

*by R***R on Reviewed in the United States on October 2, 2024*

I have only had the unit installed for 36 hours. It seems to be working. The installation was easy, but the attachment screw to the PV bracket seems flimsy. The unit is currently quite shaded, but the battery registers 0.1 volt higher than yesterday
