Unreliable BackupGas requires safe storage, and as generators need frequent refueling, this results in long queues for fuel that often run out before a major power disruption.
Limited ResourceWith a gas generator, you rely solely on fossil fuels like natural gas and LPG, which have a limited storage life and require plenty of space.
Expensive ExpansionLimited output options from 14-27kW. To expand a generator's output, the entire system needs to be replaced.

Complicated process and long wait timeThe process of choosing your solution and installation can be extremely complicated, with re-wiring and construction work that may take weeks to complete. A concrete generator platform alone may take several weeks to arrange and lay, as well as needing regular checks and maintenance every 2-3 months.

My stack…. For now I’m planning to use it only as a home backup power source which will connect to my generator panel interlock.”
Doug Renna
Brought a BMW ix home from work to test out ev charging from the DPU [DELTA Pro Ultra]. [It] had zero issues charging at 7.2kW on the 240v outlet using a standard home ev charger level 2. Gained about 10 miles or so. In an emergency, that could mean a lot. Can’t make gas at home, but you can make electricity!”

Running with 4000 watts of Ecoflow Solar panels. Can’t wait to get the second Delta Pro Ultra in the mail this week and hopefully upgrade to more solar here soon to max out both units solar input.”
Jared Wolny
Overall, super happy with this setup. I’ve had a SHP1 since release and I’ve thoroughly enjoyed being the only house on the block that has lights on during a power outage, and I used my solar to offset my energy costs.”

Those are media quotes
“ If you live in an area with frequent, brief power disruptions, this setup could make much more sense than a dedicated generator. It's cleaner, quieter, you'll never have to wrench on it, and your friends will be pretty damn impressed when you bring it to the next tailgate.”
The modular DELTA Pro Ultra can automatically switch circuits over to battery power during blackouts, scaling from a few hours of backup to a month or longer when prioritizing circuits.
