Technology: AGM
Application: Off-grid solar PV and renewable energy
Cycle life: 1,250 cycles at 50% DoD

Please check the manufacturer’s current specification before ordering, particularly where exact capacity, dimensions, terminals or charging requirements are critical to your installation.
Rolls AGM Solar Battery
AGM stands for Absorbent Glass Mat. In an AGM battery, the electrolyte is held within an absorbent separator rather than being freely contained as in a conventional flooded battery.
AGM technology can provide a practical solution for solar battery applications where a sealed, low-maintenance battery is preferred.
The Rolls AGM battery is intended for compatible deep-cycle applications where the battery is repeatedly charged and discharged.
237Ah Battery for Off-Grid Solar
The 237Ah capacity makes this battery suitable for applications requiring more stored energy than a smaller 12V battery can provide.
Potential applications include:
Off-grid solar PV systems
Remote properties
Cabins and outbuildings
Renewable energy storage
Backup battery systems
Remote electrical equipment
Leisure and mobile power applications
Larger 12V battery banks
The actual usable energy available from a battery depends on the system design, discharge rate, temperature, battery condition and permitted depth of discharge.
Rolls Battery Cycle Life
The supplied product information states:
1,250 cycles at 50% depth of discharge
850 cycles at 80% depth of discharge
Depth of discharge (DoD) refers to how much of the battery’s available capacity is used during a discharge cycle.
Battery cycle life can vary depending on operating conditions, charging regime, temperature, discharge rate and other factors.
For best results, the battery should be charged and operated according to the manufacturer’s requirements.
Solar Charging a Rolls 12V Battery
A compatible solar PV array and solar charge controller can be used to charge the battery from solar energy.
This battery is designed around a 12V nominal battery system.
For higher-power installations, multiple batteries may be configured in series or parallel where permitted by the battery manufacturer and system design.
The required configuration depends on:
Required system voltage
Inverter voltage
Required battery capacity
Maximum current
Solar charging capacity
Available installation space
Battery manufacturer’s configuration limits
Do not connect batteries together without confirming that the proposed configuration is suitable.
Battery Cables for Rolls Solar Batteries
Correctly sized battery cables are essential when connecting a high-capacity battery to an inverter, charge controller, fuse or isolator.
Our Solar Battery Cable Lengths are available in made-to-order lengths and a range of cable sizes, with terminal configurations available.
For additional battery protection, see our Blade Fuses.
Our 12V Battery Switch can provide a suitable battery isolation option where compatible with the system.
Rolls Battery and Solar Inverter
Where stored battery energy is required to power 230V AC equipment, a compatible inverter can be used.
Our 12/24V Phoenix Inverters provide Victron Phoenix inverter options for suitable battery-powered 230V AC applications.
The inverter must be compatible with the 12V battery system and its required continuous and peak power loads.
A 237Ah battery should be selected as part of a complete system rather than according to capacity alone.
The battery, charging equipment, inverter, cabling and protection should all be appropriately matched.
