Links of manufacturers and/or suppliers for this section: PDF
2.1.3.a. Flooded Lead-Acid Batteries
Specifications: 12/24/48 V nominal, minimum 100 Ah capacity at C/20 rate
Suggested Quantity: Depends on the nominal battery voltage selected (Minimum 12Vdc is required to operate smaller inverters. Real-world battery banks are often 24 or 48 volts, made up of 6-volt-deep cycle units.)
Importance Rating: Advanced.
Comments: This is an optional purchase used to operate battery-based, stand-alone and hybrid inverters.
2.1.3.b. Valve-Regulated Lead-Acid Batteries
Specifications: 12/24/48 V nominal, minimum 100 Ah capacity at C/20 rate
Suggested Quantity: Minimum 12Vdc for operating smaller inverters (Real-world battery banks are often 24 or 48 volts made up of 6-volt-deep cycle units.)
Importance Rating: Advanced
Comments: This is an optional purchase used to operate battery-based, stand-alone and hybrid inverters.
2.1.3.c. Charge Controllers
Specifications: Standard pulse-width modulated (PWM) FET based and maximum power point tracking (MPPT) controllers
Suggested Quantity: Depends on battery size and voltage.
Importance Rating: Advanced.
Comments: This is an optional purchase that may be necessary for battery-based systems.
2.1.3.d. Battery Chargers
Specifications: This is an optional purchase that may be necessary for battery-based systems.
Suggested Quantity: One.
Importance Rating: Advanced.
Comments: This is an optional purchase used to maintain batteries. Many battery-based inverters serve as battery-based chargers as well.
2.1.3.e. Generators
Specifications: 4 KVA to operate with hybrid inverter systems.
Suggested Quantity: One
Importance Rating: Advanced
Comments:This is an optional purchase for demonstrating system control for multi-mode inverters.
