Growatt SPH 8000 TL3-BH-UP

A three-phase hybrid inverter is the part that links the panels, the battery, the grid and the house and decides from second to second where the current comes from. During the day it supplies the loads from the sun and charges the battery, in the evening it takes the energy back out of the accumulator, and the surplus it sends into the grid. If the grid goes down, it switches to the backup supply so fast that the appliances do not stop.

The 8,000 W cover the consumption of a medium-sized three-phase home, and during a cut the backup output supports 8,000 W as well. You can install up to 12,000 W of panels, that is 12 kWp, 50% above the inverter power, a usual way of gaining production in the morning, in the evening and in winter. The power can be delivered entirely on a single phase, so a large load connected to one phase does not limit you to a third of the device's capacity. The high-voltage battery charges and discharges at a maximum of 25 A. The IP65 enclosure allows outdoor mounting, natural cooling means silent operation, and the night-time consumption is under 13 W.

Who it suits

Suited to a medium-sized three-phase house or a guesthouse that wants self-consumption, backup on the essential circuits and an oversized panel array of up to 12 kWp.

Terms explained

• DC/AC oversizing 1.5: You install 50% more panels than the inverter power (12 kWp on 8 kW), so as to produce more in weak light; at peak, the surplus is limited by the inverter.
• THDi under 3%: The measure of how clean the delivered current is: the lower the distortion, the better sensitive appliances work.
• RCMU: The device that detects current leakage to earth and shuts down the inverter, protecting people and the installation.

Technical details

Specifications confirmed from the manufacturer's datasheet

Growatt SPH 8000TL3 BH-UP is the 8 kW version of the SPH 4000-10000TL3 BH-UP three-phase hybrid family. It has two independent MPPT trackers, one string each, maximum DC voltage of 1000 V, MPPT range 120-1000 V (nominal 600 V) and 13.5 A maximum current per MPPT (Isc 16.9 A). The maximum recommended photovoltaic power is 12000 W, that is DC/AC oversizing of up to 1.5.

The AC output is 8000 W / 8000 VA at 230/400 V, 3W+N+PE, maximum current 12.1 A, THDi under 3% and adjustable power factor 0.8 capacitive - 0.8 inductive. The inverter delivers 100% power on unbalanced loads and allows the injection to be limited on each phase. The high-voltage battery works in the 100-550 V range (lithium or lead-acid), with 25 A maximum charge/discharge current. The backup output supports 8000 W / 8000 VA, with switching under 10 ms.

Maximum efficiency 98.2%, European efficiency 97.4%, MPPT efficiency 99.9%. Transformerless construction, IP65, natural cooling, 505x453x198 mm, 30 kg, thermal range -25...+60 C, night-time consumption under 13 W. Protections: type II SPD on DC and AC, DC isolator, grid and insulation resistance monitoring, anti-islanding, RCMU. RS485/CAN/USB communication, LCD+LED display, optional RF/WiFi/GPRS monitoring.
