Description

Growatt WIT 18kW and ALP 15.0L complete system. Secure maximum independence from rising electricity prices! With this perfectly matched hybrid set, you store your own solar power with high 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

Highest safety: The cobalt-free LiFePO4 technology of the battery storage guarantees longevity and superior fire protection.
Always supplied: Thanks to the UPS function and black start capability, your devices remain in operation 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 certified to IP66 and is therefore suitable for both indoor and outdoor installation.

The system components in detail

The hybrid inverter (Growatt WIT 18kW three-phase)
This 18kW powerhouse doesn't just convert your solar power - thanks to integrated black start capability and UPS function, it controls your entire home network. With the option for smart load control, you make optimal use of every hour of sunshine.

The low-voltage battery storage (Growatt ALP 15.0L LV battery storage)
The stackable 15kWh 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 allows for flexible capacity expansion thanks to its modular design.
