Single-Phase Grid-Tied Solar Inverter · BE2-3.6KW-1PG
Overview
The BE-2-3-3.6KW-1PG single phase solar inverter from Bexie Energy is the entry-level solution for small-scale residential solar self-consumption installations. With nominal power options of 2, 3 and 3.6 kW and 97.8% efficiency, it delivers excellent performance for homes with moderate consumption or installations being expanded gradually.
Its IP65 protection, broad compatibility with PV modules on the market and remote management via app make it a reliable, accessible and easy-to-maintain option for anyone taking their first steps in solar self-consumption.
Technical specifications of the 3.6 kW single phase solar inverter
- Nominal power: 2 kW / 3 kW / 3.6 kW
- Phases: single-phase (1PG)
- Type: grid-tie inverter
- Maximum efficiency: 97.8%
- Protection rating: IP65
- Management: remote monitoring and configuration via app
Applications of the small-power single-phase inverter
- Solar self-consumption in apartments and smaller homes
- Entry-level self-consumption installations (2-4 panels)
- Gradual expansion of existing installations
- Second homes with moderate consumption
- Installations on roofs with limited available surface area
- Self-consumption projects on a tight budget
What installation size is this inverter suitable for?
The BE-2-3-3.6KW-1PG is the ideal inverter for installations of between 2 and 4 kWp of installed PV power:
- 2 kW: suitable for 4-5 panels of 450-500W — annual consumption of up to 2,500 kWh
- 3 kW: suitable for 6-7 panels — annual consumption of up to 3,500 kWh
- 3.6 kW: suitable for 7-8 panels — annual consumption of up to 4,500 kWh
For larger installations, take a look at our single-phase 7-10 kW inverter.
97.8% efficiency — what it means in practice
With 97.8% efficiency, for every 100 kWh generated by the solar panels only 2.2 kWh are lost in the conversion process. In a 3 kWp installation in the UK, this represents an annual loss of approximately 70-80 kWh, which translates into around £20-25 per year — a very small figure that demonstrates the high quality of the equipment.
IP65 protection for outdoor installation
The IP65 rating guarantees full protection against dust and against water jets from any direction. This allows the inverter to be installed directly outdoors — on the façade, under the eaves or on the PV array itself — with no need for additional protection.
Smart management via mobile app
- Real-time monitoring of solar production
- Production history and performance analysis
- Remote configuration of system parameters

- Compatible with the Bexie Monitoring platform
Grid-tie inverter or hybrid inverter?
- This grid-tie inverter: ideal if you’re starting out in solar self-consumption and don’t need batteries right now. More affordable and straightforward. Doesn’t operate during power outages.
- Hybrid inverter: also manages batteries and can run off-grid. If you want storage from the outset, take a look at our single-phase hybrid inverter BE3.6-6KW.
Integration with the complete PV system
This inverter can be combined with our TopCon solar panels and mounting structures for a compact and optimised residential self-consumption installation. Take a look as well at our complete self-consumption solution for a tailor-made integral design. For more information on current UK regulations visit the MCS (Microgeneration Certification Scheme).
Frequently asked questions about small-power solar inverters
How many solar panels can I connect to this inverter?
It depends on the power of each panel. With 500W panels, the 3.6 kW model accepts up to 7-8 panels. For accurate sizing, please contact our technical team — it also depends on the string configuration and the conditions of the installation.
Will it work if there’s a power cut?
No. Grid-tie inverters automatically disconnect during a power outage as required by safety regulations. If you need continuity during outages, you’ll need a hybrid inverter with batteries.
Can I expand the installation in the future by adding more panels?
If you expand the array’s power beyond the inverter’s nominal rating, you’ll need to replace it with a higher-power model or add a second inverter. We recommend planning the installation with room to grow from the outset.
Is it compatible with high-current TopCon panels?
Yes, the BE-2-3-3.6KW-1PG is compatible with the leading PV modules on the market. Check the technical datasheet for the exact input voltage and current ranges supported.
Is it certified for installation in the UK and EU?
Yes, Bexie’s inverter range is certified for grid connection under current UK and EU regulations. Check the technical datasheet for the specific certifications of this model.
