Already have a Solar System and want to add energy storage?

Adding batteries to a grid-tied system is possible but can be overwhelming.

We can help you connect you to a Solar Pro in your area to help design and install the equipment you need to add energy storage to your home without jeopardizing your contract with your utility provider.

Looking for an off-grid system or a system to backup your home in case of a power outage?

Selecting the right equipment for an off-grid home or system to provide backup power for your home can be a daunting task.

We can help you connect you to a Solar Pro in your area to help design and install the equipment you need to add energy storage to your home.



The AES RACKMOUNT Energy Storage System performs reliably, installs quickly and configures easily for Off-Grid Solar, Whole-Home Backup Power and Microgrids.

Stack up to six RACKMOUNT Battery Modules with the Quick Stack Rack and parallel them with a single RACKMOUNT Battery Combiner in under 40 minutes.

Or install up to six RACKMOUNT Battery Modules in a RACKMOUNT Slimline Enclosure in under 40 minutes for outdoor use.

The Slimline Enclosure with RACKMOUNT Battery Modules installed is UL9540 DC ESS certified, enabling permitting throughout North America. 

Dramatically elevate battery charging performance by networking up to thirty-six RACKMOUNT Battery Modules in closed-loop communication with industry-leading low-voltage hybrid inverters.



Discover® Advanced Energy System (AES) LiFePO4 Lithium batteries offer bankable performance and the lowest cost of energy storage per kWh. AES LiFePO4 Lithium batteries are manufactured with the highest-grade cells and feature a proprietary high-current BMS that delivers superior peak power and lightning-fast 1C charge and discharge rates.

AES LiFePO4 Lithium batteries are maintenance-free, deliver up to 100% depth of discharge, and up to 98% round-trip efficiency. Plug-and-play installation with the best-known off-grid inverters using the LYNK II Gateway makes closed-loop communication simple and easy and dramatically improves charging performance.

UL 9540 partnerships, UL 1973 certification, a 10-year energy throughput warranty, and the capability to be paralleled to up to 148 kWh per LYNK II Gateway make AES LiFePO4 Lithium batteries ideal for solar and stationary energy storage projects.


LYNK II Communication Gateway aggregates and displays in real-time the State-of-Charge for Discover AES RACK MOUNT and AES LiFePO4 batteries. Unlock the full potential of these lithium batteries by enabling them to optimize the charging configurations of the world's best off-grid inverter-chargers and solar charge controllers.

Turn a good solar system into a great one with up to 40% improvement in 0% to 100% SOC recharging time. Remotely monitor SOC, and data log multiple sites using the data monitoring services offered by off-grid inverter systems.
