How it works

Guided solar and storage planning from first question to monitored handover.

Growatt serves homeowners, installers, and light commercial buyers who need a clear path through inverter sizing, LFP battery planning, off-grid surge loads, monitoring setup, and support documentation. The service model is intentionally conversational: translate the project into loads, constraints, and decisions before anyone commits to a model number.

Solar advisor reviewing home energy plan with installer

1. Load and bill review

We begin with the monthly electricity bill, expected backup loads, site voltage, roof orientation, and utility rules. This step prevents a common mistake: comparing inverter prices before knowing whether the project needs essential-load backup, whole-home backup, grid export, or off-grid independence.

2. Inverter and battery fit

Hybrid inverter output, MPPT voltage range, battery nominal capacity, usable kWh, surge rating, and round-trip efficiency are reviewed together. For LFP storage, we discuss cycle life, depth of discharge, EoL retention, and service access so the buyer understands the system beyond the cabinet label.

3. Installer-ready documentation

Growatt guidance turns early assumptions into a checklist for the installer: string voltage, wire path, smart meter location, transfer requirements, monitoring account setup, firmware notes, and serial number capture. The result is a cleaner handoff and fewer support gaps after commissioning.

4. Monitoring and support routine

After installation, production curves, SOC trends, alarm history, and remote firmware status help homeowners understand what the system is doing. Installers can also use monitoring records to triage problems before scheduling a site visit.

Decision support

Questions that reduce project risk

Refrigeration, lighting, communications, garage door access, pumps, and selected outlets usually come before discretionary HVAC loads. The exact list depends on breaker panel layout and battery autonomy goals.

MPPT range determines whether the PV string voltage can operate efficiently across temperature swings. Poor string planning can create clipping, low-voltage starts, or compliance problems even when the inverter size appears correct.

Before guidance

A homeowner asks for a "10 kW inverter" because a review mentioned it. The installer still needs utility voltage, roof plan, battery target, backup loads, and compliance requirements. The quote changes repeatedly, and the buyer loses confidence.

After guidance

The project starts with daily kWh use, critical-load priorities, array layout, regional grid code, and desired monitoring. The inverter family, battery bank, smart meter, and commissioning checklist are discussed as one system, making the quote easier to trust.

Even a partial bill, roof photo, or backup wish list is enough to start narrowing the system direction.
