12 volt 30/22 amp maximum power point tracking photovoltaic charge controller

Table of Contents

This manual contains important instructions for Model SB3000i - SAVE THESE INSTRUCTIONS

1. Refer installation and servicing to qualified service personnel. Incorrect installation or use may result in risk of electric shock or fire. No user

serviceable parts in this unit.

2. To reduce the risk of electric shock, fire or personal injury, the following symbols are placed throughout this manual to indicate dangerous

conditions, or important safety or operational instructions.

WARNING

Indicates dangerous conditions or electric

shock potential. Use extreme caution.

3. PERSONAL PRECAUTIONS

a) Working in the vicinity of lead-acid batteries is dangerous. Batteries produce explosive gasses during normal operation.

b) To reduce risk of battery explosion, follow these instructions and those published by battery manufacturer and manufacturer of any equipment

you intend to use in vicinity of battery.

c) Someone should be within range of your voice or close enough to come to your aid when you work near a lead-acid battery.

d) Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing or eyes.

e) Wear complete eye protection and clothing protection. Avoid touching eyes while working near battery.

f) If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters eye, immediately flood eye with running cold

water for at least 15 minutes and get medical attention immediately.

g) NEVER SMOKE or allow a spark or flame in vicinity of battery.

h) Be extra cautious to reduce risk of dropping metal tool onto battery. It might spark or short circuit battery or other electrical part that may cause

explosion.

Remove personal metal items such as rings, bracelets and watches when working with a lead-acid battery. A lead-acid battery can produce a

short circuit current high enough to weld a ring or the like to metal, causing a severe burn.

Remove all sources of power, photovoltaic and battery before servicing or installing.

4. CHARGER LOCATION & INSTALLATION

This unit is designed to charge 12 volt (6 cell) flooded or sealed type lead-acid chemistry batteries within the range of 20 to 2,000 amp-hours.

Follow battery manufacturers charging recommendations when considering this unit for use with other battery chemistry.

This unit employs components that tend to produce arcs or sparks. NEVER install in battery compartment or in the presence of explosive gases.

This unit must be installed and wired in accordance with National Electrical Code, ANSI/NFPA 70.

Over current protection for the battery must be provided externally. To reduce the risk of fire, connect to a circuit provided with 40 amp

maximum branch-circuit over current protection in accordance with National Electrical Code, ANSI/NFPA 70 with 36 cell modules, or 30 amp

maximum with 60 cell modules. Do not connect a PV array capable of delivering greater than 24 amps of short circuit current I

cell modules, or 11.8 amps with 60 cell modules.

Over current protection for the auxiliary load control output or auxiliary battery charge output must be provided externally. To reduce the risk

of fire, connect to load or auxiliary battery with 25 amp maximum over current protection in accordance with National Electrical Code,

ANSI/NFPA 70.

Insure that charge parameters are properly configured for the battery being charged as recommended by the battery manufacturer.

This unit is not water tight. Do not expose to rain, snow or excessive moisture.

Insure all terminating connections are clean and tight. Tighten Battery and PV compression terminals to 15.9 in-lb (1.80 nm), battery

temperature sensor and IPN Network compression terminals to 2.1 in-lb (0.24 nm), and auxiliary output compression terminals to 6 in-lb (0.67

nm).

5. PREPARING TO CHARGE

Never charge a frozen battery.

Be sure battery is mounted in a well ventilated compartment.

Add distilled water in each cell of a lead-acid battery until battery acid reaches level specified by battery manufacturer.
