1) RV / Marine / Golf Cart :  RV or Marine type deep cycle batteries are basically for boats & campers and are suitable for only very small systems.  They can be used but do not really have the capacity for continous service with many charge/discharge cycles for many years.  Regular or Car type batteries should not be used at all because they cannot be discharged very much without internal damage.  A very popular battery for small systems is the Golf Cart battery.  They are somewhat more expensive than deep cycle recreational batteries but are probably the least expensive choice for a small system on a budget.

2) Flooded types :  These are Lead acid batteries that have caps to add water. Many manufacturers make these types for Solar Energy use.  They are reasonably priced and work well for many years.  All flooded batteries release gas when charged and should not be used indoors.  If installed in an enclosure, a venting system should be used to vent out the gases which can be explosive.

3) Gel :  Not to be confused with maintenance free batteries, sealed gel batteries have no vents and will not release gas during the charging process like flooded batteries do.  Venting is therefore not required and they can be used indoors.  This is a big advantage because it allows the batteries to maintain a more constant temperature and perform better.

4) AGM :  Absorbed Glass Mat batteries are in our opinion the best available for Solar Power use. A woven glass mat is used between the plates to hold the electrolyte.   They are leak/spill proof, do not out gas when charging, and have superior performance.  They have all the advantages of the sealed gel types and are higher quality, maintain voltage better, self discharge slower, and last longer.  They are more expensive, but you usually get what you pay for.  You will find this type of battery used in airplanes, hospitals, and remote telephone/cell tower installations.

Why do I need one?

A charge controller, or charge 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.

Why 12 Volt Panels are 17 Volts?

The obvious question then comes up - "why aren't panels just made to put out 12 volts".  The reason is that if you do that, the panels will provide power only when cool, under perfect conditions, and full sun.  This is not something you can count on in most places.  The panels need to provide some extra voltage so that when the sun is low in the sky, or you have heavy haze, cloud cover, or high temperatures*, you still get some output from the panel.  A fully charged battery is around 12.7 volts at rest (around 13.6 under charge), so the panel has to put out at least that much under worst case conditions.

Charge controls come in 3 general types:

Simple 1 or 2 stage controls which rely on relays or shunt transistors to control the voltage in one or two steps.  These essentially just short or disconnect the solar panel when a certain voltage is reached.  For all practical purposes these are dinosaurs, but you still see a few on old systems.  Their only real claim to fame is their reliability - they have so few components, there is not much to break.

3-stage and/or PWM  Quite a few charge controls have a "PWM" mode.  PWM stands for Pulse Width Modulation.  PWM is often used as one method of float charging. Instead of a steady output from the controller, it sends out a series of short charging pulses to the battery - a very rapid "on-off" switch.  The controller constantly checks the state of the battery to determine how fast to send pulses, and how long (wide) the pulses will be.  In a fully charged battery with no load, it may just "tick" every few seconds and send a short pulse to the battery. In a discharged battery, the pulses would be very long and almost continuous, or the controller may go into "full on" mode.  The controller checks the state of charge on the battery between pulses and adjusts itself each time.

Maximum power point tracking (MPPT), These are the ultimate in controllers, with prices to match - but with efficiencies in the 94% to 98% range, they can save considerable money on larger systems since they provide 15 to 30% more power to the battery.  The MPPT controllers are even better. They match the output of the solar panels to the battery voltage to insure maximum charge (amps).  For example: even though your solar panel is rated at 100 watts, you won't get the full 100 watts unless the battery is at optimum voltage.  The Power/Watts is always equal to Volts times Amps or P=E*I (see Ohm's law for more info).  With a regular charge controller, if your batteries are low at say 12.4 volts, then your 100 watt solar panel rated at 6 amps at 16.5 volts (6 amps times 16.5 volts = 100 watts) will only charge at 6 amps times 12.4 volts or just 75 watts.  You just lost 25% of your capacity!  The MPPT controller compensates for the lower battery voltage by delivering closer to 8 amps into the 12.4 volt battery maintaining the full power of the 100 watt solar panel! 100 watts = 12.4 volts times 8 amps = 100 (P=E*I).

 Most controllers come with some kind of indicator, either a simple LED, a series of LED's, or digital meters. Some newer ones have built in computer interfaces for monitoring and control.  The simplest usually have only a couple of small LED lamps, which show that you have power and that you are getting some kind of charge.  Most of those with meters will show both voltage and the current coming from the panels and the battery voltage.  Some also show how much current is being pulled from the LOAD terminals.

BULK :  During the Bulk phase of the charge cycle, the voltage gradually rises to the Bulk level (usually 14.4 to 14.6 volts) while the batteries draw maximum current. When Bulk level voltage is reached the absorption stage begins.

ABSORPTION :  During this phase the voltage is maintained at Bulk voltage level for a specified time (usually an hour) while the current gradually tapers off as the batteries charge up.

FLOAT :  After the absorption time passes the voltage is lowered to float level (usually 13.4 to 13.7 volts) and the batteries draw a small maintenance current until the next cycle.
