Off-Grid Battery Inverters

An off-grid storage inverter is the heart of any self-sufficient system: It draws energy from your battery storage, converts it into 230-volt alternating current, and supplies power to your appliances—all without any connection to the public grid. Unlike a pure hybrid or grid-tied inverter, it is specifically designed for off-grid operation.

What makes an off-grid storage inverter unique?

Unlike grid-tied inverters, which feed solar power directly into the public grid, an off-grid storage inverter operates independently: It charges your storage system with solar power via integrated MPP trackers and draws energy from it as needed to power your appliances. This makes it ideal for systems with no grid connection or only occasional grid connection.

Our Off-Grid Storage Inverters at a Glance

The Zendure SolarFlow 2400 is an AC-coupled inverter with AI-powered energy management and 2400W off-grid power output—it learns your consumption patterns and automatically controls energy flows. The Growatt SPF6000 ES Plus is a single-phase off-grid storage inverter with 6000W output and two MPP trackers that ensure efficient energy generation even under changing light conditions.

Who is an off-grid storage inverter suitable for?

These devices are ideal for garden sheds, cabins, garages, or remote properties without a grid connection, but also serve as a backup solution if you want to remain self-sufficient during a power outage.

Frequently Asked Questions About Off-Grid Storage Inverters

• What is the difference between an off-grid and a hybrid inverter?

  An off-grid storage inverter is designed for standalone operation without a grid connection, while a hybrid inverter can also work with and feed power into the public grid.

• Do I need a grid connection for an off-grid battery inverter?

  No, that’s precisely the advantage: The device powers your loads completely independently of the public grid, using energy from your storage system.

• How many MPP trackers does the Growatt SPF6000 ES Plus have?

  The Growatt SPF6000 ES Plus features two independent MPP trackers for efficient solar power generation, even with different module orientations.

• What does AI energy management mean for the Zendure SolarFlow 2400?

  The system continuously analyzes your consumption patterns and automatically controls charging, discharging, and energy distribution to optimize your self-consumption.

• Can I retrofit an off-grid storage inverter?

  Yes, both models can be integrated into existing storage systems as long as the voltage and connection ratings are compatible. If you have any questions, our team will be happy to advise you.

• What storage capacity is suitable for which inverter?

  That depends on your daily electricity needs. As a rough guideline: The higher your output power and the longer your usage time, the larger the connected storage capacity should be.

• Does an off-grid storage inverter require approval?

  Many reporting requirements do not apply for purely off-grid operation. As soon as you connect to the public grid, you’re required by German law to register with the Market Master Data Register—it’s best to clarify this with your grid operator in advance.
