Built-in Intelligent Charge Controller: The solar charge controller adopts a dual MOS series control circuit and PWM fuzzy control which has less voltage lose, improves the charging efficiency and prolong battery life. The usb It can prevent battery from overcharge, overvoltage, discharge, short-circuit and TVS lightning protection, provide all-round protection for your use.
High Efficiency Mono Silicon Solar Cell: Monocrystalline solar panels are higher efficiencies and sleeker aesthetics. BigBlue 20w solar panels will generate current and produce a trickle charge that prevent the loss current of the battery in storage or standby process. Ideal solar power kit for variety of off grid applications including shed, cabin, gate opener, etc., where 12V batteries is used as well as charge and maintain Cars, RVs, Boats, Trailer batteries.
High Quality and Durable: BigBlue solar panel made with high efficiency monocrystalline solar cells and heavy duty anodized aluminum frame, the corrosion-proof aluminum frame and glass coating shield the panel from weathering and wear. With an IP65 waterproof( just for solar panels), it can generate electricity in most of weather.
Plug and Play: Controller comes with 3-piece SAE cable kits and connect with the attached SAE to O Terminal cable or SAE-to-Alligator Clip cable, charge and maintain your 12 volt battery in all seasons. Holes on panels are pre-drilled for fast mounting and securing, perfect for non-permanen installations and without costly structural roof reinforcements.
Environmental and Energy Saving: BigBlue 20w Solar panel charger is to convert sunlight into electric energy then charges the battery, environmental protection and energy saving.The back junction box with current protection which can prevent the battery from back current drain so that ensuring the battery stays fully charged. Comes with 12-month free technical support.
