A Solar Controller, or solar regulator is similar to the voltage regulator in your car. It regulates the voltage and current coming from the solar panels going to the battery. Most “12 volt” panels put out about 16 to 20 volts, so if there is no regulation the batteries will be damaged from overcharging. Most batteries need around 14 to 14.5 volts to get fully charged. Not always, but usually. Generally, there is no need for a Solar Controller with the small maintenance, or trickle charge panels, such as the 1 to 5 watt solar panels. A rough rule is that if the panel puts out about 2 watts or less for each 50 battery amp-hours, then you don’t need one. For example, a standard flooded golf car battery is around 210 amp-hours. So to keep up a series pair of them (12 volts) just for maintenance or storage, you would want a panel that is around 4.2 watts. The popular 5 watt panels are close enough, and will not need a controller. If you are maintaining AGM deep cycle batteries, such as the Concorde Sun Xtender then you can use a smaller 2 to 2 watt panel.         Payment & Shipment Our Services 1. Supply OEM & ODM service: Can do customer's logo packing , can develop new products according to customer’s request. 2. Supply mix container service : We can collect all different goods from customer’s other suppliers, making a mix container OR a mix parcel to arrange shipment. 3. All your questions related to our products will be replied in 24 hours.
