Frequently Asked Questions
No. The Nex E Series can operate without solar panels and can charge directly from the electricity grid.
When paired with solar panels, it stores excess solar energy for later use, helping increase solar self-consumption and reduce reliance on grid electricity.
It can also store electricity during lower-cost periods and use it when prices are higher.
The Nex E Series reduces electricity costs by optimizing electricity usage in the home. When paired with solar panels, it stores excess solar energy for later use, increasing self-consumption and decreasing reliance on grid electricity.
Even without solar panels, users can already charge during low-price periods and discharge during high-price periods through manual scheduling.
Actual savings depend on factors such as electricity tariffs, solar generation, household consumption, and usage habits.
Yes.
The Nex E Series provides up to 2600VA off-grid backup power, allowing essential household devices to continue operating during a power outage.
Typical supported loads include:
- Refrigerator
- Router / Wi-Fi
- Lighting
- TV
- Laptop
- Small household appliances
The system also supports a short-term peak output of up to 3640VA for 10 seconds, helping handle the startup surge power of common household appliances such as refrigerators, freezers, and washing machines.
NOTE:
- The total connected load must remain within the system's output limits.
- High-power appliances such as ovens, electric heaters, EV chargers, and similar devices may exceed the available backup power.
The Nex E Series is designed as a plug-and-play system and can be installed without complex electrical work.
- No modification to the household electrical panel is required
- Standard operation only requires connection to a household power outlet
However:
- Installation of accessories such as a smart meter may require a qualified technician
- Local electrical regulations should always be followed
- For the E6000 (wall-mounted version), installation should be carried out according to the user manual
Yes. The P2800 Pro supports direct solar panel connection without a separate solar inverter, using 4 independent MPPT (Maximum Power Point Tracking) channels.
The system typically supports up to 8 standard solar panels, depending on configuration. Under a typical setup, up to 2 solar panels can be connected in parallel to each MPPT channel.The total solar input capacity is up to 3600W (combined across all MPPT channels).To ensure safe operation, each MPPT channel supports:
- Voltage range: 12V – 60V DC
- Maximum current: 32A
NOTE:
- The open-circuit voltage (Voc) of the solar panel connected to each MPPT channel must not exceed 60V DC. Exceeding this limit may prevent the system from operating properly and can result in permanent damage to the product.
- Connecting solar panels in series is not permitted, as it may cause the input voltage to exceed the supported range.
- If you are not familiar with solar panel specifications, it is recommended to connect only one solar panel per MPPT channel. Before connecting multiple solar panels, please verify that the panel specifications comply with the system requirements and refer to the user manual.
Yes.
The P2800 provides up to 2400VA off-grid backup power. Typical supported loads include:
- Lighting
- Router / Wi-Fi
- Refrigerator
- Television
- Laptop
- Small household appliances
The system also supports short-term peak loads of up to 3360VA for 10 seconds, helping accommodate the temporary startup power required by appliances such as refrigerators, freezers, and washing machines.
Yes.
The P2800 Pro includes a built-in battery and supports up to 5 additional battery expansion packs.Maximum configuration:1 × P2800 Pro + 5 battery expansion packsAdding expansion packs increases total energy storage capacity and extends runtime.For example:
- Longer backup duration during power outages
- More stored solar energy available for later use
NOTE: Adding expansion packs does not increase the system's charging or output power.
The PV input rating (3600W) is the maximum solar generation capacity, not constant charging power.Actual charging depends on:
- Sunlight conditions
- Battery status
- System limits
PV input capacity (3600W) represents the maximum solar generation supported, while battery charging power is limited by system design. This is normal for all solar systems.
