Solar Battery Maintainer and charger for 12V, 18V and
24V batteries |
 |

|
This system
maintains fleet vehicle batteries and prevents sulfation when they sit idle. It
will replace self-discharge as well as clock-radio, keyless lock, and other
continuous power drains on the battery. The solar battery keeper can be roof or
dashboard-mounted and is available in 2 watts and 5 watts. Higher wattage
systems are available on request.
This PowerStream-designed circuit
uses energy harvesting techniques, so it can continue to charge the battery
even under low light conditions. Ordinary solar panels without energy
harvesting can only charge the battery when the solar illumination is intense
enough to keep the panel above 13 volts. This makes the smaller 2 watt panel
equivalent to a much bigger panel. It also prevents the battery from being
over-charged.
Thousands of these 2-watt systems are being used in
federal government installations to keep vehicles that are held in reserve
ready for service without having to have someone start and idle them on a
regular basis. This results in enough savings to result in a 6 month payback
time.
- Pulsed charging algorithm can dissolve
sulfates.
- LED flashes to show operation.
- Can extract useful power from the
solar panel even at low sun angles.
- Electronic Overcharge Protection &
back current blocking to PV panel.
- Can be used for lead acid batteries
between 6 and 28 volts, including 6V, 8V, 12V, 16V, 18V, 24V and 28V battery
systems.
- Suitable for cars, buses, airplanes,
motorcycles, boats, tractors, sail boats, motor homes and ATVs.
- 100% made in the USA, which makes
export to Canada and Mexico easy.

| It is not really realistic to expect a 2 watt (or 5 watt)
solar panel to do much charging of a big battery that has been discharged, but
it will keep a charged battery topped-off and keep it from getting
sulfated. |
