1.0 GENERAL INFORMATION
Thank you for selecting the SunSaver™ PV controller. The SunSaver is a sophisticated controller using advanced tech­nology and series switching PWM charging. The battery charging process has been optimized for longer battery life and improved system performance.
Many specifications of the SunSaver are unique. Although the SunSaver is very simple to use, please take the time to read this operator’s manual and become familiar with the controller. This will help you to make full use of the many advantages the SunSaver can provide to your PV system.
2.0 IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS—This manual contains impor­tant instructions that should be followed during installation and maintenance of the SunSaver controller.
WARNING—Be very careful when working with batteries. Lead acid batteries can generate explosive gases, and short circuits can draw thousands of amps from the battery. Read all instructions provided with the battery.
Do not exceed the voltage or current ratings of the con­troller. Use only with a 12 volt or 24 volt battery.
DO NOT
short circuit the PV array or load while connected
to the controller. This will
DAMAGE
the controller.
The controller should be protected from direct sunlight. Ensure adequate space for air flow around the controller.
Pressure terminal connectors are not required. Use only cop­per wire with minimum 75˚C insulation rating and between 10 AWG (5.2 mm2) and 14 AWG (2.1 mm2) gage.
The negative system conductor should be properly grounded. Grounding should comply with local codes.
2.1 I
NSTALLATIONS INHAZARDOUS(CLASSIFIED
) L
OCATIONS
The SunSaver family of charge controllers have been listed to UL1604 and CSA 22.2 No. 213-M1987 for use in Class I, Division 2, Groups A, B, C and D hazardous locations. In order to comply with the UL and CSA standards, the installation should follow the
5
requirements of the National Electrical Code Article 501-4(b) and/or Canadian Electrical Code Article 18-156 when installing a SunSaver in a Hazardous (Classified) Location.
WARNING: Do not disconnect while the circuit is alive
unless the area is known to be nonhazardous.
AVERTISSEMENT: Risque D’explosion—Avant De
Deconnecter L equipment; Couper Le Courant Ou S’assurer Que L’emplacement Est Designe Non Gereux.
3.0 QUICK START INSTRUCTIONS
This section provides a brief overview of how to get started using the SunSaver controller. However, please review the entire manual to ensure best performance and years of trouble­free service.
1. Mount the SunSaver to a vertical surface. Allow space above and below the controller for air flow.
2. Make sure the PV and load currents will not exceed the ratings of the SunSaver model being installed.
3. The 6 system connections to the SunSaver terminals are numbered on the label. It is recommended that the connections be made in order from 1 to 6.
4. Connect the
BATTERY
first. Use care that bare wires do not
touch the metal case of the controller.
