Part #: 735X453

NSN: 6130-01-388-0245

Restore and Maintain: Keep 12V lead-acid batteries in seldom-used outdoor vehicles and equipment ready to go any time.

Unique Design: SolarPulse's higher-quality crystalline silicon cells pack more power per square inch and have longer life than standard amorphous "thin-film" solar cells. This uniquely designed solar panel is made of highly efficient proven crystalline silicon photo-voltaic cells, encapsulated by a clear polyurethane plastic coating, and mounted on a laminated aluminum substrate back plate that is less than 1/4" thick.

Durable and Powerful Performance: It is virtually indestructible and impervious to weather and age. The SP-3 charging system provides a full 3-Watts of power in a small durable size (4.7''L x 9.45''W x 0.25''H). For ultimate performance, it should be used on a single 12V lead-acid battery to replace the power loss from electrical accessories (that occurs even when the ignition is switched off) and to reverse naturally occurring sulfation buildup on the battery plates. The SP-3 is a higher-watt version of our SP-2 Solar Charger (2-Watt). Outdoor Equipment

  • Works with all 12-Volt lead-acid batteries including VRLA, AGM, gel and flooded cell
  • Commercial-grade crystalline cells are 30% smaller per watt than and twice as efficient as typical panels
  • Maintains the normal loss of battery power on seldom-used vehicles and equipment
  • Patented Pulse Technology circuit continuously desulfates the battery 
  • Virtually indestructible commercial design
  • Dramatically reduces jumpstarts
  • Maintains the battery indefinitely without the danger of overcharging or overheating
  • Reverse polarity protected
  • LED indicates unit is working
  • Ten-Year Limited Warranty

The secret to our success is our patented pulse waveform, which removes and prevents the buildup of lead-sulfate deposits on battery plates. That primes the battery to accept and store maximum power.

Long trusted by the military, our tech is ideal for anyone who wants to get more out of their equipment.

Impressed with quality

Shipped ahead of schedule and worked as stated. Ordered and recieved XC400 and it recovered dead battery in less than 24 hours to 100%. Happy so far!

Bryan Smith
These are great for my Seadoos

I use these on my Seadoos that sit on lifts outside all year. They're perfect. I did swap the long cable/connector on the panel with the short one on the charger though. Simple splicing. I ran the now longer charger cable through the hull and up into the dry box by the handles. Now after the cover is on I can unzip the top access, open up the dry box and plug in the solar panel. I just leave it laying on top of the cover with an inch or so of cable exposed and the closed zipper entry holds it steady even in crazy weather. Love this thing!

Super easy install

Easy install on enclosed car trailer!

If you have issues with dead batteries say no more.

This thing is a power house, man this charges like there is no tomorrow. If you have issues with dead batteries say no more.

Now Even Better

Purchased my first one about 8 years ago and battery is still going strong. Just purchased another one to maintain cranking battery for a trailer mounted generator. Noticeable improvements include connectors for the solar panel and the battery cable. Appears general quality is better as well. No problems putting it into service and it's holding battery above 13.2 volts. A great product when you need to keep a critical battery ready at all times.
I have purchased several other PT products and always been happy. Uncompensated review by retired engineer.
