Tell us about your home and we'll estimate your daily load, the solar array and number of SitePulse units you need, your annual fuel cost, and the total upfront price — updating live as you adjust. Defaults are tuned for North Idaho.
Everything recalculates instantly. Search your city to localize solar production, then open Advanced settings to tune load, solar, fuel, and pricing assumptions to your exact situation.
Your home runs silently off the 1.54 kWh LFP pack (3.08 kWh with two units). Most hours of most days, nothing is burning fuel at all.
When state-of-charge drops or load spikes past the inverter, the 79cc engine runs in its 600–800 W sweet spot, tops the pack, and shuts down — far better fuel economy than a generator idling all day.
Sized for the coverage you pick, the array carries most of your annual energy. The engine simply fills the winter gap when production drops to 35–45% of summer.
A whole-home off-grid system has always meant $30,000–$50,000+ of custom battery banks, inverters, a standalone generator, and an engineered install. SitePulse delivers the same reliability as a finished product — sized, ordered, and set down like Starlink or a Powerwall.
A whole-home off-grid setup usually means a custom battery bank, a separate inverter, a standalone generator, and a solar array — all engineered, permitted, and installed by a contractor. That typically runs $30,000–$50,000+ and takes weeks of design and site visits. SitePulse packages the battery, inverter, hybrid engine, and Starlink into one finished unit. Most homes size out well under $10,000 here for the same grid-like reliability.
No. SitePulse is built to deploy like Starlink or a Tesla Powerwall — a complete product, not a construction project. There's no rack of separate components to wire together and no custom engineering for a standard setup. Connect your panels, connect your loads, and the unit manages charging, switching, and engine top-ups automatically.
Three reasons. Redundancy: if one unit ever needs service, the other keeps your home powered — you're never fully down. Storage: two packs double your battery to ~3.08 kWh, so you ride longer on solar alone before the engine ever starts. Efficiency: two right-sized hybrid engines run in short, optimal bursts instead of one oversized generator idling to cover a load you don't actually have. You only burn fuel for the energy you genuinely need.
Yes — it's battery-first. Your home runs silently off the LFP battery the vast majority of the time, solar refills it through the day, and the engine only kicks in for short top-ups when state-of-charge drops or a large load hits, then shuts back off. The result is grid-like reliability without the grid, and without a generator running around the clock.
North Idaho winter solar production falls to roughly 35–45% of summer. That's expected and already built into the estimate — the hybrid engine simply does more of the work December through February. You won't be left without power; you'll just see somewhat higher fuel use during the darkest months.
It's a solid planning estimate based on typical usage. Your real numbers depend on your exact appliances, daily habits, panel placement, shading, and local weather. When you're ready, our team will confirm the configuration and give you a firm quote — reach out any time.
