Online repair request: send the device model, battery type and the problem on WhatsApp, or use our repair request form (Persian), and our technicians will call you.
Solar inverter repair
- Overload, Over Current, Bus Voltage, Over Temperature, Fan and Ground Fault errors
- Inverters that do not turn on, have no output, beep, or keep shutting down and resetting
- Not charging the battery, not detecting PV or grid, not switching to battery or grid
- Repair of power and control boards; replacement of fans, capacitors and faulty parts
- Re-configuration of charge and output priorities
Sunverter repair (Growatt, Sako, MUST and other brands)
Off-grid inverters with a solar charger are the most common backup-power device in homes, shops and gardens around Shiraz. We repair Sako, Growatt, MUST, Foton and other brands and test them under load:
- Units that will not start or shut down when a load is connected
- Faulty MPPT section — battery not charging from PV
- Not switching to grid or battery, unusual transformer noise, overheating
- Burnt MOSFETs, IGBTs, capacitors and power boards; control and display board repair
- 12 V and 24 V inverters and home sine-wave inverters
As the official Sako representative, we service Sako sunverters with original parts.

- Not charging the battery, not switching to battery or shutting down early
- UPS battery replacement (12 V sealed lead-acid / gel) and conversion to lithium
- Service of home, computer, shop, refrigerator and elevator UPS units
Lithium battery and BMS repair
- Batteries that do not turn on, will not charge or discharge, or cut off under load
- BMS errors and lost communication between battery and inverter (CAN and RS485)
- 48 V / 51.2 V batteries that never reach full charge or empty too quickly
- Cell balancing checks, faulty cell replacement and BMS repair where economical
