Solar Charger Controllers, Desulphators, Panels
When solar panels are used to charge storage batteries (as in recreational vehicles, boats, remote monitoring and many home installations), their limited output under low sunlight conditions leads to seriously shortened battery life and performance. Trying to protect against this creates higher costs, as the typical solution is to increase the size / number of both the panels and batteries. In addition, typical solar controllers, although able to protect batteries from under/over charge, fail to optimize the charge rate capabilities of the solar panels. They also do not remove sulphate* build-up on the battery's storage plates, causing longer recharge time, boil out and shortened life.
Our BatteryMINDer model SCC015 (shown on the right) is a "Smart" Pulse Width Modulated solar charge controller-desulphator. In addition to protecting batteries from over/under charge, its unique design optimizes charge rate, ensuring batteries are recharged in the shortest possible time, keeping them at full-charge indefinitely, without ever overcharging. A patented high frequency pulse circuit continually desulphates the battery's storage plates, allowing batteries to safely accept the highest possible rates of charge in the shortest time. Because of its pulse type output and hi-lo temperature compensation, model SCC015 BatteryMINDer can be used on all types and brands of solar panels and lead acid batteries including deep cycle and sealed AGM. Model SCC015 is part of a complete battery maintenance system with both the SolarGuard battery condition monitor and a high efficiency 15-watt amorphous silicon solar panel.
*Sulphate is considered to be the major cause of reduced performance and early battery failure (Battery Council International [BCI] January 1998.
Frequently Asked Questions
| Q: What do the experts say?|
A: Here at BatteryMart.com every product is thoroughly tested. BatteryMINDer has been tested by our in-house panel of experts who compared it with major competitors. Their conclusion? BatteryMINDer is a top pick.
| Q: Is it a big seller on BatteryMart.com?|
A: YES. We've had this model in stock for nearly 5 years and have already sold hundreds of units.
| Q: Can the Solar BatteryMINDer be used to charge, maintain and desulphate any size or type lead acid 12-volt battery such as sealed gel, agm, deep cycle, marine, maintenance free electrolyte?|
A: YES, BatteryMINDer can charge, maintain and desulphate any type size lead acid based battery, regardless of construction or brand. It is however limited in power (charge current output) by the solar panel (15 watts = 15-v @ 1.0 amps). If possible, always charge your battery(s) to full capacity using a plug-in type 120 Vac input high output charger, before connecting it to your solar maintenance charger.
| Q: Can BatteryMINDer be used to maintain and desulphate more than one battery at a time?|
A: YES, but remember the limitation of the solar panel will determine how much current output your Solar BatteryMINDer can supply to the battery. Normally, up to 4 parallel connected batteries can be maintained, if they are in good condition. See our definition of a Âgood" battery in instructions for the Battery MINDer SCC015 solar maintenance charger-desulphator.
|Scientific basis for de-sulphation process / circuitry|
| Every element known to man has a magnetic moment at a resonant frequency ie, a point at which the chemical bonds that hold the molecules together to form a crystal can be broken. Sulphation, the number one cause of early battery failure, is simply crystals of lead sulphate (PbSO4) which have formed on the lead storage plates in a lead-acid type battery. |
Magnified views of battery plates:
- New battery
- Sulphated plates (Note the large crystals)
- After dusulphation using high frequency pulses
| When a battery is improperly charged (over/under) or allowed to self discharge as occurs during storage/non-use, these crystals build up on the battery's storage plates preventing the battery from ever being fully charged and therefore able to deliver their full power/capacity. |
VDC Electronics, Inc. has created a simple method of generating the required resonant frequency (3.26 megahertz pulse) to breakdown the lead sulphate crystals, allowing the molecules to return to the battery's electrolyte. By creating a wave form with the required 3.26 HHz frequency, coupled with a very fast rise time and a high amplitude pulse, more energy is developed to breakdown sulphation than by any other method believed to exist. On February 6, 2001 this unique approach was granted a U.S. Patent
Note: Not every battery is a candidate for re-conditioning due to mechanical damage, due to vibration or contamination, which has caused its cells to be ÂshortedÂ. If however a 12 volt battery has a resting voltage of at least 10.5V and none of the 6 cells are shorted, de-sulphation of its plates can be accomplished.
