Morningstar Corporation ProStar PWM Charge Controller 12/24V, 30A with Display, PS-30M

Morningstar’s ProStar is the world’s leading mid-range solar controller for both professional and consumer applications. This second generation ProStar adds new features and protections using highly advanced technology. These improvements provide longer battery life and improved system performance. The ProStar line of controllers set new standards for reliability and self-diagnostics.

The new ProStar is available in 15 or 30 amps, 12/24 or 48 volt, and negative or positive ground. The controller may be paralleled for a solar input rating of up to 300 amps. An optional meter provides an extensive display of self-testing and system status.

Features:

• PWM series battery charging (not shunt)
• 3-position battery select: gel, sealed or flooded
• Very accurate control and measurement
• Jumper to eliminate telecom noise
• Tropicalization: conformal coating, stainless steel fasteners & anodized aluminum heat sink
• Current compensated low voltage disconnect (LVD)
• LED’s indicate battery status and faults
• Capable of 25% overloads
• 5 Year Warranty

Electronic Protections:

• Short-circuit — solar and load
• Overload — solar and load
• Reverse polarity
