Bidirectional EV Charging & EV Home Backup in Cumberland

Use your EV to keep the power on. The Sigenergy DC fast charging module adds 25 kW bidirectional charging and vehicle-to-home backup to a SigenStor battery in Cumberland, Ottawa.

Back up your Cumberland home with your EV

The Sigenergy DC fast charging module (Sigen EV DC Charging Module) is a 25 kW bidirectional EV charger that stacks onto a SigenStor home battery. It charges your car straight from solar and battery DC power, and with a compatible vehicle it can send power back into your home. That is vehicle-to-home (V2H) backup: your EV becomes an extra home battery during a power outage.

Cumberland's rural and village homes can wait longer for crews after storms. Pairing your EV with a SigenStor battery stretches your backup well beyond one night.

A typical EV battery holds 60 to 100 kWh, several times more than most home batteries. Combined with a SigenStor battery, bidirectional EV charging can turn one night of backup into extended outage protection lasting days, keeping your furnace, fridge, sump pump, well pump and internet running.

How bidirectional EV charging works with SigenStor

Most EV chargers only push power one way. The Sigen DC charging module is DC coupled inside the SigenStor system, so solar, the home battery and your EV share one high-voltage DC connection. Power can flow into the car for fast charging or out of the car to run your home.

When the grid goes down, SigenStor islands your home automatically. Your home battery carries the house first, solar refills it during the day, and a V2H-compatible EV can top up the system or carry loads directly, so your backup keeps going through multi-day outages.

Everyday benefits come too: up to 25 kW DC fast charging at home, 100% solar surplus charging, battery boost charging and scheduled charging, all managed in the mySigen app.

Extended outage protection in Cumberland

Rural homes around Cumberland can wait longer for power to come back after ice storms and summer windstorms. EV backup power is one of the most cost-effective ways to stretch a battery system from hours to days.

Every system is designed by a licensed Master Electrician under ESA Licensed Electrical Contractor #7016796. We handle the load calculation, permits and ESA inspection, and install the battery, DC charging module and backup wiring in one visit.

Vehicle compatibility

Fast DC charging works with a wide range of EVs. Vehicle-to-home discharge depends on your vehicle: the EV must support bidirectional DC power, and Sigenergy enables supported models through over-the-air updates as manufacturers and standards allow. We confirm your vehicle's status before you buy, so you know exactly what backup to expect.

Frequently asked questions

Can I power my Cumberland home with my EV during an outage?

Yes, with a SigenStor battery, the Sigenergy DC fast charging module and a V2H-compatible EV. The system isolates your home from the grid and lets your EV battery help run your loads safely.

What is bidirectional EV charging?

A bidirectional EV charger can charge your car and also draw power from it. Vehicle-to-home (V2H) uses that power to run your house; vehicle-to-grid (V2G) sends it to the grid where utility programs allow.

How long can an EV back up my home?

It depends on your EV battery size and what you run. A 75 kWh EV plus a SigenStor battery can typically carry essential loads for several days, longer when solar is recharging during the day.

Do I need a SigenStor battery to use the DC charging module?

Yes. The DC fast charging module is part of the SigenStor system and mounts onto it. It can be added to a new SigenStor install or to an existing SigenStor system.

Do you install bidirectional EV chargers in Cumberland?

Yes. True Beacon Solar designs and installs SigenStor batteries and the Sigenergy DC fast charging module across Cumberland, Ottawa, with permits and ESA inspection included.
