Next Gen 2400W AC-Coupled,
Retrofit Power Storage for Every Rooftop.
One system for everyday use and peak demand.
Most appliances covered. Less grid needed.
From everyday essentials to higher-power kitchen loads, 2400W bi-directional AC helps run more of your home on stored solar.
During peak-price hours, it discharges to reduce costly grid draw.
Scale as you grow.
Start with what you need today, then expand later—ideal for future higher-demand loads like EV charging and heat pumps.
Plug & Play
Stack batteries. Connect PV. Plug into the wall. Activate in the app. Done.
Stack main unit on battery
Plug AC into wall socket
Connect Smart CT via RJ45
Higher Self-Consumption
Store surplus solar during the day and use it at night. Compared to standard micro-inverter export,
integrated storage can lift self-consumption by 60%+, maximizing the value of your solar energy.
Charge low, discharge high
Automatically charge during low-price periods (including negative prices where available)
and discharge during peaks to reduce expensive grid imports.
AI Prediction & Scheduling
ZENKI™ 2.0 learns your usage patterns and forecasts PV yield and electricity prices to automate charging and discharging:
High price:
prioritize battery discharge (incl. heat pump / EV)
Low price:
charge from the grid
Negative price:
maximize low-cost energy for home and charging

The SF2400 AC+ supports plug-and-play, user-installed grid connection.
If you want to connect this product as a non-plug-and-play device to the distribution board to participate in feed-in tariff settlement, a certified electrician must hard-wire it to a new circuit breaker and register it in MaStR as a non-plug-and-play storage inverter.
The SolarFlow 2400 AC+ cannot be directly connected to PV modules, but it can be used as an AC-coupled storage system for an existing PV system.
Yes. The Zendure App is required for system setup, selecting operating modes, and remote monitoring. Please ensure the device is connected to a Wi-Fi network for real-time data synchronization.
1. The device can be installed indoors or outdoors, but direct sunlight and rain exposure should be avoided.
2. Ensure that the device is within Wi-Fi coverage.
3. Leave at least 15 cm of space above the unit and at least 5 cm of ventilation space at the rear.
4. The installation location must be within the length range of the PV cables and the 3 m AC power cable.
5. Keep the device away from flammable or explosive materials.
6. Place the device on a stable and solid surface.
When a Zendure CT or smart meter detects excess electricity from an existing PV system feeding back into the grid, it sends a charging command to the SF2400 AC+, prioritizing storing this surplus PV energy in the battery.
Yes. This port supports connecting PV microinverters with rated power ≤ 2400 W to provide energy input to the device. However, it will only function when the device is connected to the grid.
No. The AC off-grid port is only for supplying power to loads. Do not connect a fuel/diesel/gasoline generator or any grid-mimicking power source, as this may damage the device or pose a safety risk.
Supported battery model: AB3000L
Up to 5 additional batteries can be stacked.
2400 Wh
Yes. The maximum combined charging power is 2400 W.
Yes. When the device detects a grid power outage, it automatically switches to supply power to loads connected to the AC off-grid port from the battery, providing backup power.
Yes. The AC off-grid port can operate normally even when the device is not connected to the grid, with a rated output of 2400 W and a peak output of 3600 W (200 ms).
It can work with Zendure Smart Meter 3CT, Smart Meter D0/P1, Shelly Pro 3EM, Shelly 3EM, Everhome Ecotracker IR, and HomeWizard P1 Meter, enabling automatic power adjustment.
A smart meter can monitor the household’s total electricity consumption and the direction of current in real time. When household power demand increases, it automatically raises the discharging power; when demand decreases, it lowers the output. This enables precise real-time control at the 1 W level.
The smart meter dynamically adjusts power based on real-time household load, matching electricity generation with consumption and avoiding energy feedback waste.
The RJ45 port supports RS485 communication and will enable real-time RS485 communication with the upcoming Smart Meter 3CT-S / 1CT-S.
Note: This port does not support Ethernet protocols and cannot be directly connected to routers, switches, or computer network ports.
Yes.
For long-term storage, discharge the battery to 30% and charge it to 60% every 3 months. If the battery level is below 1% after use, charge it to 60% before storage. Keeping the battery at a low charge for extended periods may cause irreversible damage and shorten battery life.
- Keep the device dry and avoid frost or freezing conditions.
- Regularly check cable connections and waterproofing.
- If the device is unused for a long period, it is recommended to recharge it every 2–3 months.
