Description
SPF-3500 ES Lite is a 3.5kW off-grid hybrid solar inverter from Growatt, designed as a compact, cost-effective entry point into off-grid and self-consumption solar systems. It combines an MPPT solar charge controller, a high-frequency pure sine wave inverter, and a UPS backup function into a single unit, giving homeowners and small installations a reliable, all-in-one power solution that works with or without a connected battery.
At the core of the SPF-3500 ES Lite is a single MPPT tracker with a wide 120–450VDC voltage range, accepting up to 22A of input current and a maximum DC input voltage of 500V. This streamlined single-tracker design keeps the unit compact and budget-friendly while still delivering solid solar harvest for smaller PV arrays — a practical fit for cabins, small homes, or backup power setups where a single string configuration is sufficient.
Built on Growatt’s proven SPF ES platform, the SPF-3500 ES Lite delivers a nominal AC output of 3,500W with hybrid operation supporting solar, battery, and grid/generator power sources. The inverter is designed for indoor installation and passive cooling, keeping operation quiet and low-maintenance. Parallel connection capability allows multiple units to be linked for expanded system capacity as energy needs grow.
Ideal for residential off-grid setups, backup power applications, and remote locations without reliable grid access, the SPF-3500 ES Lite offers Growatt’s dependable engineering in a leaner, more accessible package — a solid entry-level choice for solar self-consumption and energy independence.
