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 […]
The Anker SOLIX X1 is Anker’s modular home battery system. It’s built from a power module plus stackable 5 kWh battery modules, and several systems can run in parallel. This review uses Anker’s US product page and published datasheets. We haven’t tested one ourselves, and specs differ by region, so check the US model your […]
The EG4 18kPV is a 48V split-phase hybrid inverter that’s become a favorite for DIY-minded homeowners building whole-home solar storage. It pairs with 48V server-rack or wall-mount LFP batteries such as EG4’s WallMount Indoor 280Ah. This review uses EG4’s spec sheet and manual. We haven’t tested one ourselves. Electrical work can be dangerous: follow the […]
The EcoFlow Delta Pro Ultra sits between a portable power station and a permanent home battery. It’s a stackable inverter and battery system on wheels that can back up a whole home through EcoFlow’s Smart Home Panel 2. This review uses EcoFlow’s published specs. We haven’t tested one ourselves. Electrical work can be dangerous: follow […]
The FranklinWH aPower 2 is a 15 kWh AC-coupled home battery that pairs with FranklinWH’s aGate, a smart switch that manages grid, solar, battery and generator.

This Enphase IQ Battery 5P review is based on Enphase’s datasheet and warranty documents. The 5P is a 5 kWh, all-in-one AC battery with six built-in microinverters. Instead of one big box, you stack as many units as you need. We haven’t tested one ourselves, so there are no hands-on runtime claims here. Enphase IQ […]
Powerwall 3 vs Enphase (and FranklinWH) is the comparison most homeowners face when they get battery quotes. All three are installer-sold LFP home batteries, but they’re built differently. Powerwall 3 has a built-in solar inverter. Enphase stacks small 5 kWh units. FranklinWH offers big 15 kWh blocks with strong generator integration. Every spec below comes […]
Is a solar battery worth it in 2026? It depends on three things: how your utility credits exported solar, whether your rates change by time of day, and how much backup power is worth to you. Battery systems homeowners own and install after Dec 31, 2025 no longer get the 30% federal credit (IRS). The […]
