12V 200Ah AGM Deep Cycle Battery – Solar, Caravan & Off-Grid

For larger 12V energy-storage requirements, this 12V 200Ah AGM deep cycle battery provides approximately 2.4kWh of nominal stored energy. It is the highest-capacity option in this StarPower AGM range and is suited to substantial caravan, camper, marine, shed, backup and off-grid solar applications.

Large-Capacity 12V Energy Storage

A 200Ah AGM battery can support systems with multiple 12V loads, including refrigeration, lighting, pumps, fans, communications equipment, electronics and suitably sized inverter loads. Its larger reserve can be useful for extended stays away from mains power or installations where charging opportunities are less frequent.

Key Features

• 12V nominal voltage
• 200Ah rated capacity
• Approx. 2,400Wh / 2.4kWh nominal energy
• Sealed AGM lead-acid construction
• High-capacity deep-cycle storage option
• Suitable for solar, caravan, camping, marine and off-grid systems
• 12-month warranty

Charging & System Design

A 200Ah battery should be paired with adequately sized charging equipment. Use an AGM-compatible MPPT or PWM solar controller, mains charger or DC-DC charger with settings and charge current that follow the battery specifications. Correct cable sizing, fuse protection and secure installation are especially important at higher system currents.

Nominal vs Usable Capacity

The stated 2.4kWh is nominal stored energy. Actual usable energy and runtime depend on discharge rate, connected load, temperature, battery condition, state of charge and conversion losses. Inverter loads can draw high DC current, so confirm battery, cable and protection ratings before use.

For larger solar or touring systems, StarPower Advance Solar Technology can help match this 200Ah AGM battery with an appropriate solar array, charge controller, inverter, DC-DC charger and battery monitoring setup.
