Both are excellent batteries. The right one depends on what you’re solving for — here’s the decision the way we walk customers through it.
Battery questions usually arrive as brand questions — “Enphase or Franklin?” — but the honest starting point is what job is the battery doing: riding through outages, shifting solar into the evening, or backing up the whole house for days. Different jobs favor different architectures.
Enphase batteries are built from smaller modular units you stack to the capacity you need. Because iSolar installs Enphase IQ8A microinverters as our default, an Enphase battery speaks the same language as the rest of the system — one app, one ecosystem, one warranty family. Modularity also means you can start smaller (essentials backup) and add capacity later.
FranklinWH’s aPower units bring larger per-unit capacity and the aGate controller — a central brain that manages the home’s loads, grid connection and generator input. For households that want whole-home backup with smart load management (and potentially a generator in the mix), Franklin’s architecture is compelling.
Batteries are the newest electronics in the system — coverage matters most here. iSolar pairs storage with Solar Insure’s insurance-backed battery warranty alongside the 30-year solar warranty, so the whole system is protected by something that doesn’t depend on any one manufacturer’s fortunes.
We install and service both brands. Tell us what you want the battery to do — outage protection, bill strategy, or true energy independence — and we’ll spec both options with real numbers. Start at battery backup or get a quote.
Neither universally. Enphase’s modular AC-coupled design is elegant on Enphase microinverter systems and scales in steps; Franklin’s larger units and aGate controller excel at whole-home backup and load management. We spec both and show you the comparison.
With enough capacity and the right load management, yes — though most homes are happiest backing up essentials plus a few comfort circuits. Whole-home designs often pair storage with a generator.
No — net metering banks your surplus without one. A battery adds outage resilience and evening self-consumption; it’s a goal-based add-on, not a requirement.
Yes — modern lithium iron phosphate (LFP) home batteries are designed for indoor or conditioned installation and carry robust thermal management. Placement follows code; our licensed electricians handle it.
