Anern EVO 10.2kW Hybrid Inverter & SPI 6kW Low‑Frequency UPS Inverter in Bulgaria

Project Summary

• Date: March, 2025

• Type: Hybrid Solar + UPS‑Grade Backup Power System

• Location: Bulgaria

• Product Series: Anern AN‑SCI‑EVO Series + Anern SPI Low‑Frequency (UPS) Series

• Product Configuration: AN‑SCI‑EVO10200 (10.2kW) + SPI‑6kW low‑frequency solar inverter with UPS function

This Bulgaria project presents a “hybrid energy management + UPS backup” architecture. The EVO10200 is used for daily solar utilization and battery management, while the SPI‑6kW low‑frequency inverter strengthens backup stability and surge performance for demanding loads.

Customer Challenges

Users in Bulgaria (homes, villas, and small workshops) often require:

• UPS‑like backup continuity for routers, security systems, lighting, and home office equipment

• A system that supports higher household consumption while maximizing solar use

• Stable operation with mixed loads, including sensitive electronics and motor-type appliances

• A solution that is easy to commission and maintain for local installers

  
  

Anern Solution (Hybrid + Low‑Frequency UPS Backup)

Anern supplied a dual‑inverter configuration combining a high‑capacity hybrid inverter with a low‑frequency UPS inverter.

AN‑SCI‑EVO10200 (10.2kW) hybrid inverter

• Manages PV input, battery charging/discharging, and load supply in hybrid operation

• Enables flexible operating modes for daytime solar use and battery-backed power during grid events

• Supports larger residential and light commercial demand with a higher power platform

SPI‑6kW low‑frequency solar inverter with UPS function

• Low‑frequency topology improves surge/inrush handling and resilience under tougher load conditions

• UPS function supports backup-focused circuits requiring stable output and fast response

• Suitable for separating critical loads or heavier appliances into a dedicated, more robust backup path

Key advantages

• Two-layer reliability: hybrid daily operation + UPS-oriented backup path

• Better load adaptability: improved tolerance for high starting currents and mixed-load behavior

• Scalable planning: PV and battery capacity can be expanded without changing the core architecture

FAQ

Q1: Is this system suitable for homes in Bulgaria with frequent outages?
A: Yes. The EVO10200 supports solar + battery operation, and the SPI‑6kW provides an UPS-oriented backup path for essential circuits during grid interruptions.

Q2: What types of loads benefit most from the SPI low‑frequency inverter?
A: Loads with higher starting current (e.g., pumps, compressors, certain power tools) and critical circuits that require stable backup behavior.

Q3: Can the system be expanded later?
A: Yes. Users can increase PV array size and battery capacity, and reassign circuits between the two inverters as demand changes.

Q4: Does the setup support generator or grid as an optional backup source?
A: Yes. The hybrid side can be configured to work with grid/generator support depending on the site design and local requirements.
