Description
The Zendure SolarFlow 800 Pro 2 is a modular balcony solar battery for demanding installations – built for homeowners who want a scalable energy solution with high solar input.
- Modular system, combines with AB2000L batteries (1.92 kWh each) → start with no battery and add capacity as your storage needs grow, without having to replace the base unit.
- Supports up to four bifacial solar panels (up to 2678Wp) → higher input means faster charging and better use of limited roof area or balcony width.
- Compatible with bifacial 450W and 515W panels → choose the panel output that suits your situation and mix modules according to what's available.
The unit ships without a battery and without solar panels, but is ready to run as soon as you add the components you want. Brand-new stock with manufacturer's warranty. Ideal for anyone who values future-proofing, expandability and compatibility with high-output bifacial panels.
Questions about this unit
Do I need to register this set?
Rules differ by country and network operator — check what applies where you are. In most markets a plug-in system is notified to the local grid operator, and the battery falls under the same notification as the solar it sits behind. The paperwork is included with the delivery.
Does the output rating breach the export limit?
No. Export limits apply to the power fed into your home wiring. In the manufacturer's app you set the export to whatever your market allows; the higher rated output is used for connected loads and for internal charging.
Can I add more batteries later?
On the modular units, yes. The extra pack stacks, connects with the supplied cable and is recognised in the app after a short firmware sync. No work on your home wiring is needed. The maximum configuration is listed in the technical data.
Can it stay outside in winter?
With IP65 and cell heating, yes: discharge down to −20 °C, charging from around 0 °C, with the heater covering the range below. Choose a rain-sheltered spot on a wall and leave clearance at the vents.
How long do the rated cycles last, and what does the warranty cover?
At roughly 250 to 300 full cycles a year, 6,000 cycles is more than 15 years of use down to 80 % remaining capacity. The manufacturer warranty is listed in the technical data; your statutory rights apply on top.
How is it installed, and do I need an electrician?
Panels plug in, the unit stands on a level surface or mounts with the supplied bracket, and it connects to a standard socket. The plug-in configuration does not require an electrician. For a fixed feed-in point or metering in the consumer unit, use a qualified electrician.
