UPGRADE PATH — FOR EXISTING SOLAR HOMEOWNERS

Upgrade Your Existing Solar with AC Coupling + Sol-Ark Battery Backup

You already invested in solar. But when the grid goes down, your panels stop producing. We add Sol-Ark battery backup to your existing system — keeping your power on through every Cape Cod storm. Done in 1–2 days. No new panels needed.

Cape Cod Solar Shuts Off in Outages — The Problem Nobody Told You

When you bought solar, nobody explained that grid-tied systems are required by law to shut off during outages. Here's why — and what you can do about it.

Anti-Islanding Law

UL1741 requires your Enphase microinverters to shut down when the grid goes down. This protects utility workers from backfed power — but leaves you in the dark with $40K of solar on your roof.

🌊

Cape Cod Is Uniquely Vulnerable

Peninsula geography means single-circuit power lines with no redundant paths. The January 2026 blizzard knocked out 155,000+ connections in Barnstable County. Some areas waited 4+ days for restoration.

🔋

The Fix Is Simpler Than You Think

A Sol-Ark hybrid inverter creates an isolated microgrid on your home. Your existing Enphase panels keep producing, battery stores the energy, and an optional generator covers extended outages. All automatic.

How the Sol-Ark Battery Upgrade Works

Your existing solar panels and Enphase microinverters stay exactly where they are. We add the intelligence layer that makes them work during outages.

1

AC Coupling

Sol-Ark connects to the AC side of your existing Enphase system. No rewiring, no new panels. Your microinverters stay in place.

2

Battery Storage

EG4 LiFePO4 batteries store your solar energy. 8,000+ cycle life, self-heating for Cape Cod winters, 10-year warranty. IP65 all-weather rated.

3

Intelligent Management

Sol-Ark manages solar, battery, grid, and optional generator in one box. 5ms transfer time — you won't even know the grid went down.

4

24/7 Monitoring

MySolArk cloud dashboard shows real-time energy flow. We monitor your system remotely and catch issues before you notice them.

Whole Home Backup Power Packages

Two paths depending on what you already have. Every system is custom-designed for your home's actual load profile.

Solar Upgrade & Battery Backup FAQ

Will this work with my Enphase microinverters?
Yes. Sol-Ark is specifically designed to AC couple with Enphase IQ7 and IQ8 microinverters. Your existing panels and microinverters stay exactly where they are. Sol-Ark connects to the AC side and controls Enphase output via frequency shifting — no rewiring needed.
How long does the installation take?
Typically 1–2 days for a PowerUp Upgrade. We install the Sol-Ark inverter, mount the battery, wire the critical load panel, and configure everything. The longest part is usually the permit process (2–4 weeks), not the physical install.
I have a 5kW generator. Is that enough?
Probably not with a battery system. The Sol-Ark draws power for your home AND charges the battery simultaneously. A 5kW generator can't handle both loads. We recommend minimum 8kW for a 12K system. If your current generator is undersized, we'll help you choose the right replacement as part of the design.
What is ConnectedSolutions?
ConnectedSolutions is a program through Cape Light Compact where Eversource pays battery owners to dispatch stored energy during peak demand events (typically 5–10 summer events per year). The current rate is $275/kW — meaning a 5kW battery system earns approximately $1,375/year. We help you enroll as part of the install.
Do I still need to deal with My Generation Energy?
No. Your existing My Generation solar installation stays exactly as-is. We add the battery + Sol-Ark layer on top. Both systems coexist — Enphase handles solar production, Sol-Ark handles storage and backup. You'll have two monitoring apps: Enphase Enlighten and MySolArk.
Is the federal tax credit still available?
The federal residential ITC expired December 31, 2025. However, the Massachusetts state tax credit (15%, capped at $1,000) is still active. Additionally, ConnectedSolutions payments and SMART 3.0 production incentives can significantly improve your return on investment.
When the grid collapses, you thrive.
