What the Service Includes
On-site power station repair is a full-service procedure performed directly at your location. During the visit the technician carries out:
- detailed on-site diagnostics of all main modules
- checking battery, BMS, inverter, charge controller operation
- testing all output ports (USB-A, USB-C PD, DC, AC) under load
- measuring actual output power and voltage stability
- verifying input charging interfaces (mains, car, solar)
- thermal imaging of heating zones under load
- diagnostics of fans, thermal sensors, cooling system
- identifying causes of errors, low power, fast discharge, individual port failure
- minor on-site repairs (fuse replacement, contact cleaning, wire resoldering, error reset)
- replacement of small components (if the technician has them on hand: fuses, connectors, cables)
- software diagnostics and error reset (if access is available)
- configuration and calibration (when possible on-site)
- issuing preliminary conclusion and estimate for further repair (if battery, inverter or board replacement is needed)
- recommendations for proper operation and safe usage
The service is available for all popular models of portable power stations.
When an On-Site Technician Visit Is Needed
A technician visit is especially convenient and justified in these situations:
- the power station is heavy (500–2000 Wh and more) and difficult to transport
- the device is used as a backup power source at home, office, cottage, workshop
- there is suspicion of a minor fault that can be fixed on-site (contacts, fuse, settings, cleaning)
- the station works partially (charges but does not output AC or certain USB ports fail)
- urgent diagnostics needed before an important trip, power outage, or event
- you are located in Khmelnytskyi or within 30–40 km of the city
- station shows errors but you are unsure if the problem can be solved without replacing expensive parts
- need to verify real capacity and power output before long-term use
- issues appeared after drop, transportation, or winter storage
- want expert opinion directly at your location
A visit saves time, effort, and money on transporting large equipment.
Stages of On-Site Service
- Preliminary phone or messenger consultation (problem description, model, symptoms)
- Agreeing on convenient time and address for the visit
- Technician arrival with necessary tools and consumables
- External inspection of the station, checking housing, ports, cables
- Connection to mains and testing in charging/discharging modes
- Testing all ports under load (technician’s test equipment)
- Thermal imaging and current/voltage measurements
- Minor on-site repair (if possible): contact cleaning, fuse replacement, error reset
- Preparing preliminary conclusion and discussing possible repair options
- Issuing recommendations for next steps (service repair, component replacement, proper usage)
- Preparing work completion report and payment for visit + diagnostics
