Description

Growatt WIT 15K-HU and ALP 20.0L Complete System. Secure maximum independence from rising electricity prices! With this perfectly matched hybrid set, you store your own solar power with maximum efficiency. Thanks to the powerful backup power function, you're always reliably supplied with energy even during a grid outage.

Advantages of the Complete System

Maximum safety: The cobalt-free LiFePO4 technology of the battery storage guarantees longevity and the best fire protection.
Always supplied: Thanks to the UPS function and black-start capability, your devices stay running during a power outage.
Full power: The three-phase inverter supports 100% unbalanced load in backup mode and offers high overload capability.
Flexible & robust: The complete system is IP66 certified and thus suitable for indoor and outdoor installation.

The System Components in Detail

The Hybrid Inverter (Growatt WIT 15K-HU Three-Phase)
This 15kW powerhouse not only converts your solar power but, thanks to integrated black-start capability and UPS function, also controls your entire home network. With 2 MPPTs and the option for intelligent load control, you make the most of every hour of sunshine.

The Low-Voltage Battery Storage (Growatt ALP 20.0L LV Battery Storage)
The stackable 20kWh battery storage secures your surplus energy for the night. It uses extremely safe lithium iron phosphate cells (LiFePO4) without cobalt, offers 100% depth of discharge, and enables flexible capacity expansion thanks to its modular design.
