20W 12V Solar Battery Charger, Waterproof 20 Watt 12 Volt Solar Panel Trickle Ch

Built-in intelligent MPPT charge controller chip helps to regulate the whole charging, generating at least 10%-20% more power than competitors. Smart 3-stages of charging algorithm is improved to better charge and maintain battery at a stable level for extended battery life. Prevent the battery from overcharge, over-voltage, discharge, and short circuit, reversed polarity protection, IP65 waterproof and spark-proof, the battery is fully protected. BEWARE OF SIMILAR CHARGERS WERE SIMPLY INTEGRATED A DIODE INSTEAD OF MPPT CHARGE CONTROLLER, IT WILL NOT PREVENT OVER CHARGE, WILL CAUSE IRREPARABLE DAMAGE TO BATTERY. The LED indicator allows to visually monitor the working status and battery conditions.

The charging will be cut off when battery is fully charged and resumed automatically when battery is drained, totally free maintenance. Made of durable and strong ABS frame instead of PVC fabric, which could withstand high temperature and UV irradiation. The tempered glass help solar cells to stand high wind and load pressure, Windproof and rainproof, well built for years.

BEWARE OF CHEAPLY MADE ABS AND FABRIC SOLAR CHARGERS WHICH ARE EASILY DISINTEGRATED BY UV AND MAY CATCH FIRE. Safely used as a solar trickle charger and maintainer for different 12V DC batteries including Wet Gel Cell, Deep Cycle, Flooded, Maintenance-free, AGM, Seal Lead Acid, etc. A variety of scenarios for car, boat, ATV, RV, trailer, marine, camper, lawnmower, motorcycle, jet ski, water pump, shed, gate opener, snowmobiles, tractors, etc. Sun Energise 20 Watt 12 Volt SOLAR BATTERY CHARGER.

The solar powered battery charger is the perfect solution for charging the batteries of RV, car, boat, marine, camper, lawnmower, motorcycle, jet ski, water pump, shed, gate opener, snowmobiles, automobiles, tractors etc. When the battery is in the state of losing power and power shortage, maintaining the battery effect, extending its usage life.

Why do I choose Sun Energise Solar Battery Charger 12 volt? 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. Plug & Play SAE connector.

Each of them is equipped with SAE connector, plug and play, easy & simply to connect and disconnect. 1 X 20W Mono solar charger. 1 X Battery Clamp Cable.

1 X Cigarette Lighter Cable. 1 X Bare Wire Cable. 20W Solar Battery Charger Pro. Note: As this is 20w solar panel main function is maintain battery, not for full charging your battery. Operating Power Current: 1.1A.

Open Circuit Voltage(Voc): 21.6V. Short Circuit Current(Isc): 1.19A. Trickle Charging Current: 0.2A.

Floating Charging Voltage: 13.8V. Overcharge Protection Voltage: 14.4V. Built-in super smart MPPT charge controller, generates at least 20% -30% power than traditional PWM technology. Smart three-stage charging algorithm is improved to better charge and maintain battery.

LED work statue indicator, battery power indicator, error warning indicator, all statues are clear. Plug the cigarette lighter to socket when use it to charge or maintain vehicle's battery, really plug and play.

In some makes of vehicles, the cigarette lighter may not operate when the ignition is turned off. If so, you can connect directly to the battery using battery clamps and cables. Use the red and black battery clamps to trickle charge and maintain the 12 V battery, make sure they connect correctly. The red clamp clip is connected to the positive terminal (+) of the battery, and the black one is connected to the negative terminal (-). Don't leave the solar charger for a long time or leave it unattended. SAE To Bare End Cable. It is solid, easy to connect and disconnect, flexible to collocate. Ideal for solar battery connection and transfer, and automotive batteries transfer etc. Applied to solar panel, motorcycle, lawn motors, tractor battery, boat marine trolling motor bike, RVs, DIY etc.

What does the meaning of the LED indicator light status? The LED indicator allows to clearly monitor working status: Blink Green: Sunshine is effective (Not Active yet); Blink Red: Working to charge the battery (Activated); Solid Green: Battery is fully charged; Solid Red: Error-Reversed polarity.

Why there is No current (Amp) or DC Voltage out of the solar panel? Unlike regular solar panels, the solar battery charger you ordered was built-in intelligent MPPT charge controller chip and improved 3 stages of charging, there is no way to test any output when it is inactive, this is the reason why you got zero voltage reading. However, you can add a multimeter inline to test charge current, like the way to test an electrical battery charger.

I left the solar battery charger in my car for a week and it doesn't charge anything? For some makes or models of vehicles, the cigarette lighter port may not operate when the ignition is turned off.

In such case, you can connect directly to the battery terminals using the alligator clamp or bare end cable provided. Can I use it to charge a almost dead battery?

No, it was designed for 12V battery, so if your battery is below 6V, it will cause failure to activate the solar charger. It is a solar battery trickle charger that keeps the voltage from dropping or recharges the battery, but it is not a fast charger and cannot charge a dead battery.

Pls use the AC charger to fully charge the battery before using the solar panel.
