Before you order.
If yours isn't here, ask an engineer. It costs nothing and it's the step most people skip.
Is the racking or mounting hardware included?
No. Rails, roof hooks, ground-mount posts and clamps depend on the roof or ground they go on, so no system ships with them. They are sold separately. The finder adds the right pack for your surface when it sizes a system, or ask us and we will match one to your roof.
Can I install it myself?
The equipment ships ready to connect, but the AC side, the grounding and any connection to the grid must be done by a licensed electrician. A grid-tied or hybrid system also needs a permit and your utility's interconnection approval before it is switched on. The wiring diagram and commissioning record we publish are for reference; they are not a stamped design, and a professional engineer's review is required where your jurisdiction calls for one.
Are the solar panels included?
Where the title names an array — “7.04 kW panels”, say — the panels are in the box and appear under What ships. A backup system whose title names no array, such as the Growatt whole-home and partial-home backup systems, is the inverter and battery only, and its listing says so. Panels for those are sold separately.
What is the difference between off-grid, grid-tie and hybrid?
An off-grid system has no utility connection: the battery carries the night and the generator input carries the dark days. A grid-tie system has no battery: it feeds your panel and the grid by day and goes dark in an outage. A hybrid system does both — it works with the grid and keeps a battery, and with its transfer switch it carries your essential circuits through an outage.
Which tax credits and incentives apply?
The 30% federal residential credit ended on 31 December 2025, and nothing on this page assumes it. Some states still run their own credits, sales-tax exemptions or generation payments; the savings estimate above lists the ones we know of for your state, and our tax credit guide explains what applies in 2026.
Can I charge from a generator?
Most off-grid inverters in the range have a generator input for charging on dark days; the specification table says whether this one does and at what current. A grid-tie inverter has no generator input. A hybrid system takes a generator through its transfer switch, if your electrician wires one in.
What if I'm not sure this is the right product?
Ask before you order. Send us what you need to run, or your pool or well figures, and an engineer will confirm the choice — it costs nothing. Or use the finder below, which sizes from what you actually run and shows its reasoning.
