We're solving for the optimal mix of assets that makes your property grid-autonomous, antifragile to blackouts, and generating income from the grid every day it's running.
Most properties here depend entirely on the grid. When a nor'easter takes out power lines, everything stops. Solar panels? They shut off too. By law, grid-tied solar must disconnect during outages to protect utility workers. Your $40,000 solar array sits idle while you sit in the dark.
A standalone generator is better than nothing, but it's still one source. It runs until it runs out of fuel. It can't charge itself. It wears out running 24/7. And it ignores the free solar energy already on your roof.
We solve this differently. We design an optimal mix of three assets — solar, battery, and generator — managed by a single brain, that generates cash 99% of the time and provides seamless backup the other 1%.
Job: Generate free energy. Charge the battery. Sell surplus to the grid via net metering. During outages, keep charging the battery so the generator doesn't have to.
Job: Primary backup power. Cash generator via Connected Solutions ($275/kW/year). Handles 95% of outages alone without ever starting the generator.
Job: Last resort. Runs 1-2 hours to refill the battery during extended outages, then shuts off. Sized to minimize runtime, not just cover load.
The only inverter that natively manages solar + battery + generator + grid in one box. 5ms transfer time. When the grid drops, your lights don't flicker. Your clocks don't reset. You find out about the outage from a notification on your phone or from Eversource — not from your house going dark.
While the grid is running — which is 99% of the time — your solar and battery are revenue-generating assets. Solar produces energy that offsets your electric bill through net metering. Your battery earns annual income through Cape Light Compact's Connected Solutions program, dispatching stored energy during peak grid demand. A 5kW battery earns roughly $1,375/year just for being available.
When the grid goes down, those same cash-generating assets stop selling to the grid and simply power your home or business for as long as it takes. The switchover happens in 5 milliseconds. While the rest of the neighborhood is out of power or scrambling to start their generators, you're only aware of the outage because your app sent you a notification.
This is the key insight: These aren't backup systems sitting idle waiting for a storm. They're working assets generating income every day. Backup is a feature of the system, not its purpose.
95% of Cape Cod outages last less than 7 hours. A properly sized battery bank handles those without ever starting the generator. No fuel burned, no noise, no intervention. You don't even know the power went out.
For extended outages — multi-day storms, the January 2026 blizzard that knocked out 155,000+ connections — the generator kicks in. But here's how we size it differently than everyone else:
We oversize the generator relative to the load. Not to power more stuff. To charge the battery faster. A generator running at 85% load factor is at peak efficiency. It runs for 1-2 hours, fills the battery back up, and shuts off. Then you're back on battery with solar topping it off during the day.
Why this matters: During storms, generators are noisy. Minimizing runtime means less fuel consumption, faster battery recharge, and less noise for you and your neighbors. An oversized generator running 1-2 hours beats an undersized generator grinding away for 8.
The formula is straightforward: Minimum Generator kW = Home Load + Battery Charge Load. The Sol-Ark draws power for both simultaneously. A 5kW generator will overload when the inverter tries to charge the battery on top of your home load. For a Sol-Ark 12K, minimum practical generator is 8-10kW. For a 15K, it's 16-22kW. We size this properly in every design.
0-5 milliseconds: Grid goes down. Sol-Ark detects the loss and isolates your home from the grid. Battery takes over. Your lights stay on. Clocks don't reset. No interruption.
Hours 1-7: Battery powers your home. Solar (if daytime) continues charging the battery. For 95% of outages, this is the entire event. Generator never starts.
Hour 7+ (extended outage): Battery SOC drops to 20%. Sol-Ark auto-starts the generator. Generator runs at ~85% load, powering the home and charging the battery simultaneously. Battery reaches 90% SOC. Generator auto-stops. You're back on battery + solar.
This cycle repeats as long as the outage lasts. Generator runs 1-2 hours, battery carries 6-10 hours (longer with solar). Fuel lasts for days, not hours. Meanwhile, the rest of the town is running generators 24/7, burning through fuel, and listening to the noise.
Most Cape Cod solar installations use Enphase microinverters. You don't replace them. Sol-Ark connects to the AC output side of your existing system. Panels stay, microinverters stay, nothing gets rewired on the roof. This is called AC coupling, and it's why an upgrade is a 1-2 day install, not a full re-do.
During outages, Sol-Ark controls your Enphase system through frequency shifting — managing output to prevent battery overcharge while keeping solar production running. Your existing solar investment becomes part of the microgrid.
Nassim Taleb defined three categories: fragile things break under stress, robust things resist stress, and antifragile things get stronger from stress.
Grid-only power. One failure point. Breaks every storm. No income generation.
Generator backup. Resists failure. But burns fuel, degrades over time, generates no income. A cost center.
Solar + battery + generator. Generates income daily. Handles outages seamlessly. The worse the grid gets, the more valuable the system becomes.
Your battery earns money through Connected Solutions when the grid is stressed. Your solar earns credits through net metering every sunny day. When the grid fails, those revenue-generating assets seamlessly switch to powering your property. The system doesn't just survive disorder. It profits from it.
The worse Cape Cod's grid infrastructure gets, the more outages there are, and the more your system earns from demand response, and the more value it provides in avoided downtime. That's antifragile.
Every Sol-Ark system includes lifetime access to the MySolArk cloud platform. Real-time power flow, battery state of charge, solar production, grid import/export, generator runtime, and fault alerts. Mobile app on iOS and Android. 5-minute data intervals.
This is how you know the power went out — your app tells you, not your house. For commercial clients and property managers with multiple sites, fleet-level monitoring shows every system across every property from one dashboard.
Our free estimator sizes a system based on your property's load, your existing solar, and your backup requirements — then shows you the economics.
