Growatt SPF5000 ES

This device is an off-grid inverter, that is one that supplies the loads from the panels and the battery, without sending energy into the public grid. In a single enclosure there are three things: the inverter itself, which produces current of the same quality as the one in the socket, the regulator that extracts the energy from the panels and the charger that can fill the battery from the grid or from a generator. The UPS function means that the transfer to the battery is done automatically, so the appliances do not stop when the power fails.

The power of 5000 W covers the usual loads of a house or of a cabin, and the peak of 10.000 VA, that is double the power, allows the starting of pumps, compressors or power tools. The panel field can reach 6000 W, and the 48 V battery is charged from the sun with up to 100 A or from the grid and generator with up to 80 A, so it fills quickly even on days without sun. You can choose the priority order, that is whether the energy comes first from the sun, from the grid or from the generator, both for charging and for supplying the house. If you need more power, up to 6 units can be connected in parallel. The device has IP20 protection, so it is mounted only indoors, in a dry and ventilated space, it has an LCD display and can be monitored remotely with an optional WiFi or GPRS module.

Rated power 5000 VA / 5000 W, peak 10.000 VA, output 230 V a.c. +/-5%, 50/60 Hz, pure sine wave, maximum efficiency 93%. A single MPPT, maximum open-circuit voltage 450 V, MPPT window 120-430 V, maximum PV field power 6000 W, maximum solar charge current 100 A, charging from AC or generator up to 80 A, with configurable priorities for charging and for supplying the loads. Battery 48 V, LiFePO4 lithium with BMS communication or lead-acid. Size 330 x 485 x 135 mm, about 12 kg, IP20 for indoor mounting, LCD display, optional WiFi or GPRS monitoring, paralleling up to 6 units; being an off-grid inverter, it does not inject energy into the public grid.

Who it suits

Suitable for a cabin or a house without a grid connection or with an unstable grid, with single-phase consumption and a 48 V battery, where the device can stay indoors.

Terms explained

• Off-grid: System that works independently of the public grid; it produces and consumes locally, without selling surplus into the grid.
• Pure sine wave: The form of the delivered current is identical to that in the socket, so sensitive appliances can also be safely supplied, such as the refrigerator, the boiler or the computer.
• IP20: Enclosure protected only against touching with a finger, without water protection; the device must be mounted exclusively indoors.

Technical specifications

Recommended applications

• Houses and cabins without a grid connection
• Back-up for homes with an unstable grid
• Isolated guesthouses and workshops
• Hybrid systems with a backup generator

Technical details

Specifications confirmed from the manufacturer's datasheet

Growatt SPF 5000 ES is a single-phase off-grid inverter that integrates in a single enclosure a pure sine wave inverter, an MPPT solar regulator and a grid charger with a UPS function. The rated power is 5000 VA / 5000 W, with a peak of 10.000 VA for starting inductive loads such as pumps, compressors or power tools.

The photovoltaic input has a single MPPT tracker, with a maximum open-circuit voltage of 450 V and MPPT window 120-430 V; the maximum power of the PV field is 6000 W. The maximum charge current from the panels is 100 A, and charging from the grid or generator can reach 80 A, with configurable priorities (solar, grid or generator) both for charging and for supplying the loads. The battery is 48 V and accepts LiFePO4 lithium batteries (with BMS communication) or lead-acid.

The output is 230 V a.c. +/-5%, 50/60 Hz, pure sine wave, and the maximum efficiency reaches 93%. Up to 6 units can be connected in parallel to increase the power. The enclosure of 330 x 485 x 135 mm and approximately 12 kg is intended for indoor mounting (IP20), with an LCD display and optional monitoring through WiFi or GPRS. Being an off-grid inverter, it does not inject energy into the public grid.
