Product Detail

Company Profile


The 7000W nominal capacity accommodates typical residential rooftop arrays up to 10kW DC with 1.4-1.5 DC/AC ratio optimization. Dual MPPT architecture with independent tracking enables two separate string orientations or tilts—maximizing roof utilization without orientation-mismatch losses. Each MPPT channel handles 11-22A input current and 200-1000V voltage window, supporting high-wattage bifacial modules and long string configurations that reduce BOS cabling costs.
Three-level T-type inverter topology minimizes switching losses and filter size—achieving 98.6% maximum efficiency and 98.1% weighted CEC efficiency across 5-100% load range. Wide voltage operation maintains MPPT functionality from dawn to dusk, capturing energy during low-irradiance periods when conventional inverters remain offline. Reactive power capability supports grid stability requirements with 0.8 leading to 0.8 lagging power factor adjustment.
Intelligent cooling management employs variable-speed fan control with temperature-predictive algorithms—maintaining full power output at 50°C ambient without derating. IP65 enclosure rating permits outdoor installation without additional shelter, with corrosion-resistant aluminum housing for coastal environments. Integrated DC and AC surge protection (Type II) safeguards against lightning-induced transients without external SPD installation.
Grid interaction features include anti-islanding protection per IEEE 1547/UL 1741, frequency-watt and volt-watt ride-through for weak grid support, and remote monitoring via Growatt ShineWiFi or ShineLAN communication modules. Real-time data visualization through ShinePhone app includes energy yield, system status, and fault diagnostics with push notification alerts.
Safety systems encompass ground fault detection, residual current monitoring (30mA sensitivity), and arc fault circuit interrupter (AFCI) with string-level fault location—reducing fire risk and enabling rapid maintenance response. DC reverse polarity protection and AC short-circuit protection provide installation-error immunity and long-term fault tolerance.
Compact mechanical design (435mm × 330mm × 175mm) with 19.5kg weight enables single-person wall mounting. Push-in DC terminals with MC4-compatible connectors reduce commissioning time, while hinged wiring compartment simplifies maintenance access. 5-year standard warranty extendable to 10 or 20 years through service contracts.
