Growatt Hybrid Solar Inverter WIT8K-X-HU 8KW Three Phase Energy Storage Inverter For Residential Solar Power System
$1,420.00
The Growatt WIT 8kW-X-HU inverter is a three-phase hybrid solar inverter designed for residential and small industrial applications. It is known for its affordable price and high quality. The inverter is certified for the global market and is commonly used in pro-consumer installations. It comes in various capacities ranging from 8kW to 15kW.
One of the key features of the SPH inverter is its backup output for EPS (Emergency Power Supply) circuits and possibility to work with LOW VOLTAGE (48V) batteries
This output can operate in two modes:
- Bypass mode, where power is constantly supplied to the EPS output,
- UPS (Uninterruptible Power Supply) mode, where power is available after a power outage, enabling off-grid operation.
To further enhance its functionality, Growatt offers the option to pair the WIT inverter with AXE energy storage systems. These energy storage solutions have capacities ranging from 5.1 kWh to 30,6 kWh. By combining the Growatt WIT inverter with AXE energy storage, users can maximize self-consumption of the energy generated. Instead of sending excess energy to the grid, it is stored in the batteries, reducing reliance on energy prices set by the distribution company. This setup promotes greater energy independence.
The Growatt WIT inverters are compatible with LiFePo4 batteries and backup power systems, providing flexibility for various energy storage configurations. Additionally, when combined with an energy meter, the WIT inverters can activate the export limit function, allowing users to regulate the amount of energy they export to the grid. This feature enables the generation of energy balances for the entire building, promoting efficient energy management.
Overall, the Growatt WIT 8kW-X-HU inverter offers a cost-effective and high-quality solution for residential and small industrial applications. Its hybrid capabilities, EPS backup output, compatibility with ARK energy storage, and ability to activate export limits make it a versatile choice for those seeking efficient energy management and greater energy independence.
