Growatt SPF 3000 ES 3kW Off-Grid Solar Inverter

Description

The Growatt SPF 3000 ES is a multi-functional 3 kW off-grid solar inverter integrated with an 80A MPPT solar charge controller and a high-frequency pure sine wave inverter module. It manages power flow dynamically by combining energy from solar PV panels, 48V energy storage batteries, and utility grid power (or generator supply) to feed continuous single-phase power to critical electrical loads.

Capable of operating with or without a battery bank connected (utilizing high PV input voltage up to 450VDC), it is designed for homeowners, rural telecom sites, commercial stores, and offices seeking power independence. In Bangladesh, where grid instability and frequent load shedding interrupt everyday operations, the SPF 3000 ES guarantees stable, uninterrupted power while trimming reliance on grid electricity.

Key Features

• Integrated 80A MPPT Controller: Tracks maximum power points efficiently up to 450VDC PV array input to maximize daylight harvesting.
• Battery-Free Operation Mode: Allows system startup and power delivery directly from high-voltage solar panels to connected loads even when no battery is attached.
• Grid & Solar Hybrid Charging: Configurable charging priorities allow simultaneous or prioritized battery charging via solar PV and utility grid.
• Pure Sine Wave Output: Provides clean, stable single-phase 230V AC output suitable for sensitive electronics, inductive motors, and home appliances.
• Parallel Scalability: Supports parallel operation (up to 6 units) to scale total system capacity as power demands expand.

Technical Advantages

• High Conversion Efficiency: Pure sine wave topology ensures peak efficiency up to 93% with low internal loss.
• Durable Construction: Heavy-duty enclosure designed to manage thermal heat via intelligent speed-controlled cooling fans.
• Safety Protection: Comprehensive protection suite including overload, short-circuit, deep battery discharge, and reverse polarity protections.
• Energy Saving: Smart power-saving mode reduces idle self-consumption when no load is detected.
• Easy Maintenance: Front LCD display panel and detachable dust filters simplify regular maintenance and system diagnostics.

Applications

• Residential: Homes, apartments, and villas requiring reliable backup power during load shedding.
• Commercial: Retail shops, superstores, bakeries, and customer billing counters.
• Industrial: Small workshops and light machinery setups needing uninterrupted control power.
• Factory: Security posts, IT servers, and administrative units within factory compounds.
• Office: Single-phase corporate workstations, routers, and desktop computer networks.
• Project Installation: Off-grid rural electrification, telecom towers, and remote solar projects in Bangladesh.

Installation & Maintenance Guide

Installation Requirements:

• Wall-mount vertically on a non-combustible concrete or metal wall capable of holding 11.5 kg.
• Ensure clear space (at least 20 cm above and below, 10 cm on sides) for effective fan ventilation.
• Use appropriate 48V battery cabling and copper DC solar wire sizes with matching DC circuit breakers.
• Ground the inverter casing firmly to a proper earthing pit to protect equipment against voltage surges.

Maintenance Tips:

• Clean the removable side dust filters periodically to prevent internal thermal throttling.
• Check battery terminal connections every 6 months to ensure tight contact without corrosion.
• Use the Growatt ShinePhone mobile app to track battery state of charge (SOC) and historical power generation logs.

Safety Instructions:

• Installation must be conducted by a certified electrician or experienced solar technician.
• Disconnect all PV solar strings, battery breakers, and AC mains inputs before inspecting connections.
• Do not expose internal wiring to water or operate the inverter with damaged cable insulation.
