Growatt SPF6000 ES PLUS

This is the device that takes the place of the electrical grid in a house supplied by panels and batteries. It takes the energy from the sun and from the batteries and transforms it into the ordinary current from the socket, and if needed it can also use a generator or the grid as a backup source. When the supply fails, it switches so quickly that the electronic appliances do not even feel the interruption.

The 6,000 W power covers at the same time the usual loads of a home, and the peak of 12,000 VA, that is double the rated power, helps to start the motors of pumps, water pressure sets or power tools, which for a few seconds demand much more current than in normal operation. The panel field can reach 8,000 W, so more than the inverter power, which helps in the morning and on cloudy days. The 48 V battery can be lithium LiFePO4 or lead-acid, and from the menu you choose the order in which the sources are used: sun, grid or generator. The unit weighs about 13.5 kg, is installed indoors and works between 0 and 55 °C, with optional WiFi or GPRS monitoring.

6000 VA / 6000 W nominal, peak 12,000 VA. Maximum PV input 8000 W, open-circuit voltage 500 V, MPPT window 120-450 V, 2 MPPT with one string each, maximum solar charging current 100 A. AC input 230 V, 50/60 Hz with automatic frequency detection; output 230 V +/-5%, pure sine wave, PF up to 1.0; UPS switchover 10 ms typical, 20 ms maximum; maximum efficiency 93%. Paralleling up to 6 units; overall size 460 x 395 x 132 mm, approx. 13.5 kg, 0...55 °C.

Who it suits

Suitable for a house, a guesthouse or a workshop without a grid connection, with medium-high consumption and with motors that have to be started (pump, water pressure set), where a generator exists or can be added.

Terms explained

• MPPT: The circuit that permanently searches for the point at which the panels give the most power; two MPPT means you can have two groups of panels oriented differently, tracked separately.
• Peak power (12,000 VA): The power the device can deliver for a few seconds, above the normal one, just enough to start a motor or a compressor.
• UPS / 10 ms switchover: The automatic switch to the battery when the supply fails, so fast that the computer or the fridge do not stop.

Technical specifications

Recommended applications

• Off-grid homes with medium-high consumption
• UPS backup for houses and offices
• Guesthouses, farms and isolated workshops
• Hybrid solar + generator systems

Technical details

Specifications confirmed from the manufacturer's datasheet

Growatt SPF 6000 ES Plus is the 6 kW version of the off-grid ES series, improved with two independent MPPT trackers and an increased photovoltaic input. The rated power is 6000 VA / 6000 W, with a peak of 12,000 VA when starting motors and pumps.

The PV field can reach 8000 W, with a maximum open-circuit voltage of 500 V and an MPPT window of 120-450 V, one string on each of the 2 MPPTs; the maximum solar charging current is 100 A. The 48 V battery can be lithium LiFePO4 (with BMS communication) or lead-acid, and the priority of charging and of supplying the loads (solar, grid or generator) is set from the device menu.

The AC input accepts 230 V, 50/60 Hz with automatic frequency detection, and the output is 230 V +/-5%, pure sine wave, with a power factor up to 1.0. In UPS mode the switchover time is approximately 10 ms (maximum 20 ms), sufficient for IT and refrigeration equipment. The maximum efficiency is 93%. Up to 6 units can be paralleled to extend the power. The dimensions are 460 x 395 x 132 mm, the weight approximately 13.5 kg, and the operating temperature 0...55 °C; installation is indoors, with optional WiFi or GPRS monitoring.
