A critical loads panel is a separate subpanel that holds only the circuits you want powered during an outage, such as the fridge, Wi-Fi, lights, furnace blower and well pump. Your battery or generator feeds that panel, not the whole house. That lets a smaller system cover what matters and avoids overloads from big appliances. […]
Home battery backup without solar works. The battery charges from the grid and takes over during outages. It can’t refill itself in a long blackout, though, and with no 25D credit for homeowner-owned systems after 2025, the math has to stand on backup value or rate savings alone. Here’s when it makes sense. Electrical work […]
How much does a Powerwall 3 cost installed? Tesla gives location-specific quotes through its design tool and certified installers. Consumer guides published in 2026 commonly report around $15,000–$16,000+ for one unit installed, before incentives, but your number can be higher once electrical upgrades are added. Here’s what goes into the price and how to compare […]
Transfer switch vs interlock is the key decision when you connect a generator or portable battery to your house. Both do the same essential job: they make it impossible to feed power back onto the utility lines, which can kill line workers and damage equipment. They differ in cost, convenience and how many circuits you […]
Generac vs Powerwall 3 often comes up for homeowners who already know Generac for standby generators. Generac’s current home battery is PWRcell 2, a modular AC-coupled system. Tesla’s Powerwall 3 is an all-in-one battery with a built-in solar inverter. Here’s how they compare on the makers’ published specs. Generac vs Powerwall 3: Specs Spec Generac […]
Victron ESS explained simply: ESS (Energy Storage System) is a mode on Victron’s MultiPlus-II and Quattro inverter-chargers that turns a battery bank into grid-tied home storage. A GX device (like the Cerbo GX) and a grid meter tell the inverter how much to charge or discharge so your home uses its own solar first and […]
