Easy Setup in Clear Steps
Connect. Install. Power Up.
Stack the batteries. Connect PV. Hardwire to the consumer unit. Activate in the app. Done.
*Hardwired installation must be carried out by a Part P-qualified electrician.
PV generation + Energy storage
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.
Energy Arbitage (TOU/dynamic tariffs)
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

Installation & Connection
How is the system installed?
Fully certified under ENA G98 to comply with UK industry regulations, the SolarFlow 2400 Pro requires installation by a Part P-registered electrician. To support compliant installation, the system comes standard with hardwiring terminals.
Has the SolarFlow 2400 Pro obtained ENA G98 certification?
Yes. The SolarFlow 2400 Pro has fully passed ENA G98 certification and is officially registered.
What specifications of cables should be used to connect the PV panels to the device?
It is recommended to use PV cables with a cross-sectional area of ≥4 mm². When installed in conduits, they can carry approximately 25 A or more, and local electrical codes should be followed.
Is a Wi-Fi connection and the Zendure App required?
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.
What are the requirements for the installation environment?
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.
Solar & Generation
How to select PV panels?
Each independent MPPT input supports:
- Module rated power ≤ 660 W
- Short-circuit current (Isc) < 22.5 A
- Open-circuit voltage (Voc) ≤ 55 V
It is recommended that the total PV module power connected to each MPPT does not exceed 1.5 times its rated power (approximately 1 kW) to balance power generation efficiency and system stability under different weather conditions.
Can the AC off-grid port be connected to a PV inverter?
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.
Can the AC off-grid port be connected to a fuel generator?
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.
Can the SF2400 Pro be used without connecting PV panels?
Yes. Even without a solar PV system, you can charge the storage battery via the grid. This allows you to take advantage of dynamic electricity pricing, charging during low-demand periods to reduce energy costs.
Battery & Charging/Discharging
Which battery models are supported?
Supported battery model: AB3000L
Up to 5 additional batteries can be stacked.
Built-in battery capacity:
2400 Wh
Does the device's battery support safe charging in low-temperature environments?
Yes. The device features a low-temperature self-heating function. When the ambient temperature drops below 0°C, the system automatically activates a heating mechanism to warm the battery to a normal charging temperature range, ensuring safe charging and discharging in cold conditions.
Can the PV panels and battery supply power simultaneously?
Yes. The maximum combined charging power is 2400 W.
Does it support EPS functionality?
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.
Can the AC off-grid port be used when the device is not connected to the grid?
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).
Smart Control & Grid Integration
Which smart meters can SolarFlow 2400 Pro work with?
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.
How does a smart meter work?
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.
How does a smart meter help achieve “zero energy waste”?
The smart meter dynamically adjusts power based on real-time household load, matching electricity generation with consumption and avoiding energy feedback waste.
What is the purpose of the RJ45 port on the device?
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.
Does it support Home Assistant?
Yes.
Seasonal maintenance
How should the device be stored?
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.
Winter operation precautions:
- 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.
