RATED POWER 20 WATTS

Intended for 12-volt systems only, the M20 regulates its electrical output to the needs of the battery. Self-regulation eliminates the need for separate charge control devices, resulting in a simple, reliable and economical power generating system.

Siemens solar electric modules are tested to meet or exceed industry standards, and even more rigorous Siemens quality and performance requirements.

10 YEAR WARRANTY
The Siemens M20 solar electric module carries a 10-year limited warranty on power output. Utilizing the highest standard of construction, it is able to withstand some of the most severe environments in the world and continue to perform efficiently.

• Tough, multi-layered polymer backsheet is used for environmental protectiojn, resistance to abrasion, tears and punctures.
• A single junction box with cable is designed for easy field wiring.

» 009B

APPLICATION
Specially designed for open/drainback solar systems.

FEATURES
• 27 foot shut-off head.
• Flows to 10 GPM.
• Companion flanges ¾” to 1 ½” or ¾” sweat connection.
• Low power consumption.

March’s proven magnetic drive eliminates the troublesome, old-fashioned shaft seal. There can be no seal wear, power-robbing friction or leakage through the seal. Impeller and drive magnets are permanent ceramic type. They prevent slippage and insure that full motor horsepower is converted into pumping power. Energy requirements are lowered, as all the energy produced by the motor is utilized, especially important in solar systems. March seal-less drive also provides for faster, easier motor service, as the motor can be removed without draining or refilling. Their low starting current and high efficiency make them excellent for stand-alone solar circulators.
