If you've ever gotten your RV from storage and found it with a dead battery, this Optimate solar system is a perfect solution. It provides an easy way to charge your RV batteries and keep them in good working order with clean, renewable power. Using the 10-watt solar panel, this system collects solar energy to create DC power that passes through a solar charge controller and into your battery. The kit includes adapters to suit your charging application.


When your RV is parked, position the panel where it can receive direct sunlight and leave it plugged in. The solar controller will monitor the battery, maintaining it and preventing it from being overcharged. This is also a great choice for maintaining the battery in your motorcycle, ATV, golf cart, or other big toy. Simply mount the panel to the roof or wall of your garage and run the cables inside.


Polycrystalline Solar Panel


Optimate solar panel installed on a roof

The charging process starts with the solar panel, which mounts permanently with screws or other mounting hardware (sold separately). When solar energy interacts with the silicon cells in the panel, it generates a flow of DC electrical current that charges your battery. And in optimal sunlight conditions, the panel produces 10 watts per hour.


Smart Solar Controller Charges and Protects Battery

The solar controller prevents harmful overcharging by adjusting the power generated by the solar panel before it reaches your batteries. It uses pulse width modulation technology to regulate the output through pulses that provide a consistent charge. Typically, PWM controllers are a good fit for smaller systems with lower voltages compared to more expensive MPPT solar controllers.


Using a multistage charging system, the controller automatically switches voltages while the battery bank charges. This accelerates the charge, but also helps extend battery life by adjusting the voltage during the different modes. The controller is compatible with multiple battery types and includes preset charging profiles for sealed/gel, AGM, and flooded/wet cell lead acid batteries.


Charging Modes

  1. Save: When battery save mode is in progress, the solar charge controller is detecting a battery lower than 12V. It can save a battery discharged as low as 4V.
  2. Charge & Optimize: In this mode, the controller will be actively charging the battery. The battery is optimized by continuing charging for at least 10 more minutes.
  3. Maintain: The battery will be maintained in this mode as the charger delivers a holding voltage between 13.3V and 13.6V.

Optimate solar charge controller

LED indicators provide information on the current solar panel output. The lights will tell you if the panel is providing a charge, if the battery is deeply discharged and in save mode, if the battery is moderately charged and in charge & optimize mode, and when the battery is fully charged and being maintained. It automatically detects battery type and chooses the appropriate charging profile.


Easy-to-Use Adapters for Battery Connection


Optimate cables for attaching panel to battery

This kit includes two cables for temporary or permanent attachment to your battery. The SAE plugs connect to the charge controller and attach to your battery using ring terminals or alligator clips. The ring terminals are good for creating a port on your motorcycle, ATV, golf cart, or RV so you can park it and quickly attach the solar panel with zero fuss. The alligator clips are a good option if your battery is easily accessible and you only occasionally plan to hook up the solar panel.

Great service, speedy delivery and fine products.

It's a great solar charger. The only downside is that it doesn't indicate the charging level. I have it hooked up to my four wheeler in a remote area to keep the battery charged. It would be a five rating if there was some way to tell if the battery was fully charged when using the charger.



by:

service was excellent, product was just as described.



by:

Product has been great! Keeps the battery on my jetski charged and ready, no longer worry about getting to the ramp with a dead battery



by:

Got the 20 watt panel to maintain the dual batteries in my motorhome.
So far, so good. Great build quality. We'll see how it does in winter.



by:

I have bought one of these before. I liked it well enough to buy a second one. My motorhome has two batteries in the coach, so now I have one solar panel for each battery.

Product exactly what was advertised and easy to install.

  • Will 10 Watt Solar Panel Charge Batteries in Parallel
    Hi Douglas, Yes, you can charge a pair 12 volt batteries wired in parallel with a 10 amp solar panel like the OptiMate Solar Duo Solar Charging System - Roof Mount # MA49JR or Portable # MA69JR. You will keep them wired in parallel and this will allow a sufficient trickle charge.

  • Will A Solar Panel System Help With Winter Battery Storage In The Trailer
    I typically recommend removing the battery from the trailer and storing it in the garage for a bit of warmth and keeping it on a small charger to keep it topped off so that it doesn't end up getting damaged, but a solar panel kit can help keep the battery charged so that the electrolytes don't have the opportunity to change from acid to water and freeze. A typical AGM battery will discharge about 2% per month so a smaller solar panel kit like the OptiMate Solar Duo Roof Mount Solar Charging...

  • Solar Panel Recommendation for Trickle Charge on Winch Battery
    I recommend installing the OptiMate Solar Duo Roof Mount Solar Charging System with Controller # MA49JR which is rated for 10 Watts and 12V batteries from 2 to 240 amp-hours. This provides a trickle charge and comes with a controller so you can be confident that your battery will get a good charge but won't become overcharged.

  • Is It Normal For 12v Power To Be On The Trailer Side 7-Way Plug When Disconnected
    Hey Phil, It's ok to see 12 volts on one specific pin (pictured below). It means that whoever wired it ran a line to the battery so that the 12v hot pin on your tow vehicle's 7-way can charge the trailer battery a bit while you tow. Power sitting in the wire can drain the battery but it's such a low amount that it would take a long time to really drain the battery. Typically on trailers there's a lot of other appliances (lights, monitors, etc.) that have a small drain which all together...

  • Recommended Solar Panel System For Trickle Charging Two Boat Batteries
    You're on the right path but this kit # 34282183 has items you don't need if you're just looking to trickle charge your boat batteries.

  • Is The Bright Way Solar Charger BRW54FR Compatible With Lithium Batteries
    We do carry a solar battery charger that is lithium compatible, but the Bright way # BRW54FR you mentioned cannot be used with lithium batteries. Instead I recommend the OptiMate Solar charging system # MA49JR. This includes a 10 watt panel and charger and will be compatible with your 12v 100 amp lithium battery.

  • Can the OptiMate Solar Duo Solar Charging System with Controller Be Extended
    When using the OptiMate Solar Duo Solar Charging System with Controller # MA49JR, the manufacturer does recommend not extending the wire. But, they do mention it can be done if absolutely necessary under a few conditions. 1: The pins on the plug of the extension cord are the same number, size and shape as those of plug on charger. 2: The extension cord is properly wired and in good electrical condition, and 3: The conductor wire size is large enough for the DC ampere rating of the charger We...

  • Could Optimate Solar Duo Panel Kit Work on Camper Van
    Hey Joy, yes the Optimate Solar Duo kit part # MA49JR would work on a camper van but whether or not it would work well is goin to be based on the power needs of your setup. This is a 10 watt setup which means it's not going to put a big charge on the van battery. 10 watts is equal to .83 amps in ideal sun conditions. A 100 watt system like the Go Power part # 34272635 is probably more in line with what you'd need. This would put a much more significant charge on the battery setup of your van.
