Utility Surcharge Avoidance

The introduction of advanced energy storage, lithium chemistries, has revolutionized the market for grid-connected solar. More than simply pushing energy to the grid, modern residential solar systems require intelligence and controls that can respond to changing and varied grid-connection and safety standards and manage behind-the-meter energy consumption to reduce power bills.

Lithium AES LiFePO4

Manufactured with the highest-grade cells and a proprietary high peak surge and transient voltage hardened BMS, Discover´s Advanced Energy System (AES) LiFePO4 lithium batteries offer bankable performance and the lowest cost of energy storage per kWh. AES LiFePO4 batteries are maintenance-free, deliver 100% depth of discharge, up to 98% round-trip efficiency, and are backed by an unlimited cycle 10-year energy throughput warranty.

Lithium PRO LiFePO4

Lithium PRO batteries feature self-heating, a proprietary high current battery management system, and lightning fast 1C continuous charge and discharge rates. Purpose-built to be continuously operated in a partial state of charge (PSOC) without degrading performance. Tested and certified to the highest safety and performance standards.

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

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 Batteries

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.

Rural Microgrid Batteries

Large capacity energy storage combined with localized generation to create an autonomous electric grid that will support a farm, resort, commercial operation, or multiple residences.
