Home Battery Size Guide: How Much Capacity Do You Actually Need?
Battery capacity is about matching your evening load and backup goals — not buying the biggest unit. Here’s how to size one honestly.
How Much Do Home Batteries Cost? Pricing for 2025
Batteries are the biggest add-on cost in home energy. Here’s a transparent look at pricing, the chemistry difference, and installation.
AC vs DC Coupled Batteries: What’s the Difference?
Batteries can connect to your solar on the AC or DC side — and it changes efficiency, cost and whether you can retrofit. Here’s the honest comparison.
Whole-Home Backup vs Essential Loads: Sizing a Backup System
Do you want the whole house on backup, or just the essentials? The difference changes battery size, inverter power and cost dramatically.
Home Battery Installation: Process, Location & Safety
Where a battery can go, what installation involves, and the safety and compliance points that matter. A practical guide for homeowners.
Tesla Powerwall vs Enphase: Home Battery Compared
Two of the most popular home batteries compared honestly — capacity, power, backup, monitoring and which fits different setups.
Home Battery vs Backup Generator: Which Is Right for You?
Batteries run quietly on stored energy; generators deliver power for as long as fuel lasts. Here’s the honest decision framework.
Battery Payback: Will a Home Battery Pay for Itself?
The honest math on battery payback — arbitrage savings, backup value, incentives, and when the numbers work.
How Home Batteries Work: Chemistry, Flow & the Smart Software
What actually happens inside a home battery — cells, chemistry, the battery management system, and how software decides when to charge and discharge.
Battery “Arbitrage”: Making Money Charging Cheap, Using at Peak
Arbitrage means charging a battery when power is cheap and using it when power is expensive. How it works, whether it pays, and the honest maths.
