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 […]
How many batteries to power a house depends on two numbers, not one. Energy (kWh) decides how long you last. Power (kW) decides what you can run at the same time, including the startup surge of an AC or well pump. Most homes run out of power capacity before they run out of energy. Electrical […]
Solar lease vs buy got more complicated in 2026. The 30% federal credit for homeowner-owned systems (Section 25D) ended for systems placed in service after Dec 31, 2025. Third-party-owned systems (leases and PPAs) may still qualify for a business credit (48E) for the owner, under rules that are still changing. That shifts the math between […]
The Tesla Powerwall 3 is Tesla’s third-generation home battery, and the first with a built-in solar inverter. This review uses Tesla’s US datasheet and installation manual for every spec, explains how the Expansion unit works, and covers which homes it suits. We haven’t tested one ourselves, so there are no hands-on runtime claims here. Tesla […]
Generator vs battery backup for home comes down to how long your outages last. A generator runs as long as there’s fuel. A battery is silent, instant and fume-free, but it runs out unless solar refills it. Many homes end up using both. Electrical work can be dangerous: follow the manual, fuse and size every […]
Grid-tie vs hybrid vs off-grid is the first design decision in any home solar project. It decides whether you need batteries, what happens in a blackout, and roughly what you’ll spend. Here’s how each type works and who it suits. Electrical work can be dangerous: follow the manual, fuse and size every cable correctly, and […]
NEM 3.0 is the nickname for California’s Net Billing Tariff (NBT). The California Public Utilities Commission (CPUC) adopted it on Dec 15, 2022 (Decision 22-12-056). It applies to PG&E, SCE and SDG&E customers who submitted an interconnection application on or after April 15, 2023. The utilities call it the “Solar Billing Plan.” Its main change […]
Microinverters vs string inverters is the main equipment choice on most residential solar quotes, and power optimizers sit somewhere in between. All three turn panel DC into home AC. They differ in where that conversion happens, which changes shade performance, monitoring, safety compliance and what fails over 25 years. How Each Works Microinverters vs String […]
