KEHUA SPI8K-B Inverter – 8 kW
A single-phase grid-tied inverter designed for photovoltaic installations of up to 8 kW. The unit is fitted with two independent MPPT inputs, full AC/DC surge protection and extensive remote communication options, making it a suitable solution for both domestic installations and small commercial premises.
Key features
2 independent MPPT inputs
Two independent maximum power point trackers allow strings of panels with different orientations or tilt angles to be connected. Each string is optimised separately, which reduces losses caused by partial shading or mismatched module parameters.
AC/DC surge protection and IP65 rating
Integrated lightning protection on both the direct current and alternating current sides removes the need to install external surge protection devices as separate components. The IP65 rating means the unit is fully dust-tight and resistant to water jets, so it can be installed outdoors without an additional enclosure.
I&V Curve Scan and fault identification
The built-in current-voltage (I&V) curve analysis function allows faulty or underperforming photovoltaic panels to be detected and located remotely. This shortens installation maintenance times, with no need to physically check each module individually.
Industrial-grade components and 25-year lifecycle
All electronic components used are of industrial grade, which translates into the 25-year full lifecycle declared by the manufacturer. This figure matters when planning the return on investment and maintenance schedules for PV installations.

Applications
- On-grid photovoltaic installations in single-family homes
- Small commercial and service-sector installations
- PV systems with panels at different orientations or exposures (thanks to 2 MPPTs)
- Installations where the inverter has to be mounted outdoors
- Sites with remote monitoring and diagnostics requirements
- Installations in areas with variable grid voltage parameters (LVRT function)
Communication and remote management
The inverter supports three communication protocols at the same time: RS485 (wired, for local monitoring systems and meters), Wi-Fi (wireless access to the manufacturer's app) and GPRS (data transmission over the mobile network in locations without Wi-Fi access). Remote software updates (OTA) remove the need for a service visit when deploying firmware patches.
LVRT function – operation at reduced grid voltage
Low Voltage Ride Through (LVRT) is a function that allows the inverter to keep operating during temporary voltage dips on the distribution network, instead of disconnecting immediately. It is required by network operators in many European countries — its presence is a condition for obtaining a grid connection for installations above a certain capacity. Before purchasing, the current requirements of the local distribution network operator (DNO) should be verified.
