ABC Service — Backup Power

Backup Power

Battery backup, standby generators, and transfer switches for grid resilience.

ABC Service designs backup systems around your real loads — not a marketing brochure — so the critical circuits stay up when the grid drops.

Not just new equipment — a system done correctly.

Battery Backup Installation

ABC Service installs Tesla Powerwall, Enphase IQ, and FranklinWH battery systems with whole-home or critical-load backup. Batteries cover outages and reduce time-of-use bills — two payoffs from one piece of equipment.

Battery sizing reflects measured critical-load consumption, not nameplate guesswork — refrigeration, internet, lighting, well pumps, and medical equipment as relevant. Stacking multiple batteries is straightforward when the original install anticipated it, which is why we always wire for expansion.

Standby Generator Installation

We install natural-gas standby generators from Generac and Kohler for homes and small commercial sites where long, multi-day outages are a real concern. Sizing matches measured load, not nameplate guesswork.

Standby generators are sized against a measured load profile and configured for the natural-gas pressure the utility actually delivers under cold-start demand. Monthly self-test logs and quarterly inspection are part of the package — a generator that hasn't been tested is a generator that won't start.

Automatic transfer switch and critical-load sub-panel installed by ABC Service on a concrete wall with tidy conduit and organized breakers.

Transfer Switch & Sub-Panel

We size manual and automatic transfer switches and build critical-load sub-panels so the circuits that matter stay live. Transfer equipment, grounding, and interconnection are done by code, every time.

Automatic transfer switches are wired with full equipment-bonding compliance and configured for the specific source-priority and re-transfer logic the homeowner wants. Manual transfer setups are designed so anyone in the household can operate them safely during an outage.

Service & Monitoring

Our team services existing battery and generator systems — firmware updates, monitoring reviews, and load-profile analysis — so the backup actually works when the grid drops.

Long-term support covers firmware updates, monitoring-portal reviews, capacity testing, and recommendations as household loads evolve. Backup systems are only as good as their last test cycle, and we track that schedule so the homeowner doesn't have to.

Why it matters

Why this is worth doing right.

Outage resilience

PSPS events and storm outages are now a planning assumption, not a rare exception.

Right-sized backup

Most homes don't need whole-home backup. A well-designed critical-load setup costs a fraction and works.

Stacked value

Batteries cover outages and reduce time-of-use bills — two payoffs from one piece of equipment.

Safety

Transfer switches, grounding, and interconnection protect line workers and your equipment. Done by code, always.
