Rural Microgrid Batteries
Solar Energy Storage
Home

The main concern for rural microgrid batteries is the amount of useful energy capacity and the ability to scale up capacity to meet autonomy needs. The battery’s charge/discharge efficiency and useful energy versus system design life calculation will have a significant impact on the project’s economics.

Energy Storage Tubular Cells

Discover® Energy Storage Tubular Flooded (OPzS) and Gel (OPzV) provide superior deep cycling performance and reliable energy storage for rural microgrid and renewable energy applications. OPz batteries, with tubular plate technology, extends lead-acid battery service life significantly by providing excellent recovery during deep discharge and frequent Partial State of Charge operation.

Battery Comparison & Cost Calculator

Having difficulty explaining the real cost of energy storage options in a way your customers can understand? Discover’s Energy Storage Cost Calculator is a tool for installers that compares CAPEX vs OPEX of the major storage chemistries used in off-grid solar over a 10-year period.

Compare AES lithium to other lithium, tubular or lead acid battery systems. All you need is the manufacturer’s data sheet and battery specifications. Discover’s Energy Storage Cost Calculator generates a printable report that will help you demonstrate the impact of battery chemistry choice on your customer’s total cost of energy storage.

Additional Solar Energy Storage Applications

Utility Surcharge Avoidance Batteries

Store on-site renewable and electrical grid energy during times of low demand and low utility rates for consumption later avoiding peak period surcharges.

Residential Off-Grid Solar Batteries

Store energy generated by on-site renewables to support autonomous living or small commercial and farming operations without a connection to the electric utility grid.

Whole-Home Backup

Store energy to power your home during blackouts or weather-related grid outage and enable self-consumption of renewable energy to avoid peak period utility rates.
