Redoubt Charging Options

Off-Grid 

Grid Down Redoubt Off Grid ESS

Off-Grid is when you are getting power from an alternate energy source like solar panels, generator, wind power, or hydro power. This alternate energy source can be used to charge the Redoubt energy storage system and power your home directly.

Grid-Tied

Grid Down Redoubt Grid Tied ESS

Grid-Tied is when you are getting power directly from the power grid. With the Grid Down Redoubt, the electrical grid can be used to charge the Redoubt energy storage system and also power your home directly.

Combination

Grid Down Redoubt Grid Tied and Off Grid ESS

A combination system is when you are connected to the grid and also getting power from an alternate energy source. With a combination system, you can charge the redoubt from both power sources and also power your home from both power sources.

Basic System Architecture

This figure depicts the basic application of the Grid Down Redoubt System. Power is fed into the system from the power grid, solar power array or generator to have a complete running system.

Grid Down Redoubt App

Advanced Metrics
Monitor current and past energy usage, turn features and/or products on and off at the touch of a button, and set up custom controls to tailor your Grid Down Redoubt to your needs.

Monitor Current and Past Energy Consumption
See what energy is coming in and going out from both your solar system and Grid Down Redoubt. Look at past energy data by the hour, day, week or month so your system can be more efficient. Make individualized adjustments to create the best experience for yourself.

Set up Personalized Controls
Connect your devices and control the functionality of your Grid Down Redoubt from a distance using Bluetooth Technology. Remotely turn on or off your batteries so you’re not wasting any energy.

Automate & Save
For your Grid Down Redoubt, use the app to automate recharge times to only draw energy from the grid during off-peak hours. Create specific intervals to recharge you Sanctuary batteries, whenever is best for you.

Control Your System
Be ready for a home blackout or a big storm, winterize your RV, or turn your solar generator off or on.

Redoubt Benefits

Load
Management

Accumulate energy when the demand is low and discharge stored energy during peak times, saving money.

Backup Power/
UPS

Supply backup power in case of an electrical grid failure until complete power restoration. Save time and money by eliminating downtime.

Renewable Energy
Integration

Open the door to inexpensive electricity continuously available to on-grid, off-grid, and hybrid systems.

Power System
Recovery Capability

Based on battery storage, a Redoubt can restart after a total shutdown without using external electricity networks. Recover in the shortest time possible.

Energy
Time-Shift

In areas where electricity prices fluctuate, energy is purchased at a low price during off-peak periods and sold or used when the price increases.

Frequency
Control

Immediately react to power interruptions and stabilize the grid. It can also ensure voltage stability, maintaining its level within the specified range.

Better Capabilities. Better Solution.
