Low-voltage PV kit comprising: Deye SUN-8kW 3-phase hybrid inverter & Felicity FLS48100SG2 battery storage unit with 10.24 kWh capacity

The low-voltage PV kit, comprising the Deye SUN-8K-SG04LP3-EU 3-phase hybrid inverter and 1x Deye SE-F5C Pro battery storage unit, offers a high-performance, all-in-one solution for modern residential photovoltaic systems. With an inverter output of 8 kW and a high-quality lithium iron phosphate battery with a storage capacity of 5.12 kWh, the system enables a high level of self-consumption, reduced electricity costs and greater independence from the public grid.

The Deye SUN-8K-SG04LP3-EU features two independent MPPT trackers, supports 48 V low-voltage batteries and enables intelligent energy flows between the photovoltaic system, the battery storage unit and the domestic mains supply. The Deye SE-F5C Pro reliably stores surplus solar power and makes it available again when needed – for example, in the evening or, if appropriately configured, as part of a backup system.

FAQs on the low-voltage PV kit with Deye SUN-8K and SE-F5C Pro

Which PV systems is this kit suitable for?

The kit is ideal for domestic photovoltaic systems with an inverter output of up to 8 kW and offers an efficient solution for storing surplus solar energy.

What are the advantages of a hybrid inverter?

A hybrid inverter combines a photovoltaic system, battery storage and the domestic mains supply in a single unit. This allows solar power to be consumed directly, stored or used later from the battery.

Can the battery storage system be expanded?

Yes. The Deye SE-F5C Pro has a modular design and can be expanded with additional compatible storage modules, allowing the storage capacity to be flexibly adapted to energy requirements.

Is an emergency power supply possible?

Yes. The Deye SUN-8K supports a backup or emergency power function. This requires professional installation and the appropriate electrical design of the system.

Who is authorised to install the PV kit?

The electrical connection of the hybrid inverter, the battery storage system and the grid connection must only be carried out by a qualified electrician.
