User questions & answers

Question: Ok should the controller flash when hooked up to my car battery all the time which is the - then battery both flash is that normal
Answer: The weak point in this system is the controller. I would unhook it and put it in the round file, order a Zamp controller and install it. You will get better readings on your daily collection of amps, battery voltage, and you can use it with LA, LiPo and AGM batteries by choosing the internal settings. No it shouldn't flash, I set mine on a shelf as an emergency back up and installed a Zamp 10 Amp. More expensive, but more quality and more amps to your battery.

User questions & answers

Question: Will this charge two deep cycle battles at the same time
Answer: I don't know where the 2 other comments came up with one amp output. Minimum is 5.1 amps with mttp controller. Still insufficient to fully charge deep cycle flooded battery with much load.
Question: Are there any directions with this item? also, do i peel off the plastic coating? it is all bubbly like i should, but i am not sure
Answer: No, there are not really any directions but it’s pretty simple to use. Yes, peel off the protective plastic layer. I know it looks like it is attached underneath the fabric but it comes pretty easily.
Question: how long will it take with good sunlight to recharge a dead 12v automotive battery
Answer: The right answer is: It won't. 5W is the absolute best these cheap panels will output, in reality you will only get about 1W during daylight hours, mostly due to thermal derating. The charge will be so minimal, that battery leakage at night will eliminate any small charge you get during the day.
Question: Does this have a blocking diode
Answer: I don't believe this panel has a blocking diode built in as CX wrote in 2018. Can seller confirm whether there is a blocking diode built into the panel? Thanks

Sunway solar battery trickle charger maintains the charge of car, truck, marine, tractors, ATVs, snowmobiles, boat,water crafts or RV 12 volt battery!

Why do I need a solar trickle charger?

  • Batteries Naturally Discharge - Automotive batteries naturally discharge when not in use.
  • Vehicles have a small but constant battery drain - Modern vehicles have upwards of 30 body control modules (computers), alarm systems, immobilizers and lock monitoring. These units all consume electricity from the battery. That's why in a week or two with no or little vehicle use the battery can become discharged.
  • Battery life is shortened if it is not kept charged - A 12V battery that is not correctly maintained above 12.4V can suffer from sulphation. Sulphation is the main cause of battery failure. That's why the auto battery easy goes to dead when vehicles are left standing for long periods.

User questions & answers

Question: How long are the wires
Answer: I think the wires that came with the unit are probably 6 feet long but if you need more length you can purchase an extender. Keep in mind the less the voltage must travel the more efficient the charger will operate.
Question: What is the wire awg? 14awg or 16awg
Answer: This is a small current Its wires can support its current There won't be any problems
Question: can I use this for light in my barn
Answer: You could if you connected it to a small 12v battery and used some of the 12 LED retrofit light kits they use for the interior of cars or an 12v led strip. I'd suggest maybe a 12v CCTV battery to make it affordable. Unless you are talking about large amounts of light, then you probably would be better off with some kind of pre-made solar light kit.
Question: Does this unit have a charge profile controller for lead acid batteries, they prevent over charging & shut down the current as battery approaches 12v
Answer: It has no controller. But if you charge small batteries, you need a controller. If you charge a large battery, you don't need a controller because its current is relatively small and it won't cause overcharging.

User questions & answers

Question: Why is the wire on the pos side so short? I’m having trouble finding branch connectors long enough to connect two panels
Answer: Agreed. Makes no sense to have one cable so short. It also makes no sense to have diodes in opposite directions. Connecting 2 panels is a pain in the ass trying to find branch connectors. Renogy geniuses at work.
Question: Where are the panels made
Answer: their manufacturing video suggest asia: https://www.youtube.com/watch?v=AKC3iSrzntQ
Question: Can I use this to charge jackery
Answer: Absolutely. I charge my Flashfish 300W and it provides for basic lights and equipment use. I can use lights, pump, water heater, printer, laptop and phone all from my daily charge.
Question: How do i attach panel to a fabric bimini. i didn’t realize there are not any holes in edges of panel before i purchased
Answer: Bought two panels after using cardboard cut-and-tapes to posted dimensions to check fit on bimini. Checked cable route and run length with rope. Received the panels/cables and laid them out on bimini for 2nd fit check, positioned and outlined with chalk. Removed the bimini and a friend sewed two-inch velco hook tape onto the bimini, just inside of the chalk lines while I glued the opposing two inch wide loop tape around the perimeter of the panel bottoms using Marine Goop adhesive and putty knife. Waited two days for the adhesive to cure and while waiting, mounted the 100/30 Blue Solar charge controller, connected that to the battery ACR (automatic charge relay charging both house and start batts) and then connected the pre-measured panel cables. Then put the bimini back up, dropped the panels on (covered them with a towel to reduce chance of shock) and plugged them in! Removed the towels and watched as my batter monitor showed amps flowing into my batts! Those panels are on there good, but can still be removed for whatever reason. Sewing job on bimini and adhesive on panels have not budged in winds up to 30 kts, so far.

User questions & answers

Question: How long are the hook-up cables
Answer: These are made in Riverton, Wyoming.
Question: Are the battery cables completely divided as per the photo.? My car requires long and separated cables
Answer: You can use a Brunton transit in Ecuador if you get the international model. If you get a standard model, instead, you'll probably need to have the needle balanced to work in the southern hemisphere.
Question: Will this keep a trolling motor battery charged? can i leave it connected as i use the motor? thanks
Answer: A far as I know, the Brunton transit measures only in degrees, with two versions available: one azimuth model with 0-360 degrees on the compass face, and one with four 90-degree quadrants on the compass face. If they make a special model for the military, I'm not aware of it.
Question: Is there actual built-in circuitry to prevent overcharge, or do you have to buy that separately
Answer: It takes less than 1 minute if you have the tool (a small tiny key) fot it and know the angle of inclination of your current location.

Sunway solar battery trickle charger maintains the 12 volt battery of car, truck, marine , motorcycles , tractors, ATVs, snowmobiles, boat or RV.

Why do I need a solar trickle charger?



Three reasons to own a Sunway Solar Battery Trickle Charger:

  • Batteries Naturally Discharge - Automotive batteries naturally discharge when not in use.
  • Vehicles have a small but constant battery drain - Modern vehicles have upwards of 30 body control modules (computers), alarm systems, immobilizers and lock monitoring. These units all consume electricity from the battery. That's why in a week or two with no or little vehicle use the battery can become discharged.
  • Battery life is shortened if it is not kept charged - A 12V battery that is not correctly maintained above 12.4V can suffer from sulphation. Sulphation is the main cause of battery failure. That's why the auto battery easy goes to dead when vehicles are left standing for long periods.
