Six years as a field engineer for a residential battery storage company left Maria with a very specific frustration: the gap between what installers tell homeowners about batteries and what homeowners actually need to know. She studied Electrical and Computer Engineering and writes with that same technical grounding, covering storage capacity, inverter types, backup configurations, and what a battery system realistically does and doesn't do during a power outage. Straightforward, no upsell, just the information needed to make a good decision.
