Inverter Commissioning in Karachi, for Every Brand
Get Free Quote WhatsApp UsSwitched On Is Not the Same as Commissioned
An inverter that powers up is not necessarily set up right. Commissioning is the set of checks and settings that make it run safely, at full output and with the right protection: grid settings, firmware, battery parameters, export limits and monitoring.
SunnyPath Energy commissions on-grid and hybrid inverters of every major brand, on our own installations, on inverters customers have bought themselves, and on systems another installer left unfinished.
What Gets Missed When Commissioning Is Rushed
Many of the inverter faults we are called out for were never hardware faults. They were settings: the wrong grid standard, battery parameters left at factory defaults, export limits that were never set, or a data logger that was never connected, so nobody noticed the system underperforming for months.
Proper commissioning catches these on day one, before they turn into tripping, low generation or a damaged battery.
Every Brand, Set Up by People Who Repair Them
We commission Huawei, Solis, Growatt, Sungrow, GoodWe, Deye, Fox ESS, Sofar, SAJ, INVT, Chint, Auxsol, Fronius, SMA, Inverex, Knox, Ziewnic, Crown, MaxPower, Fronus, Itel and SolarMax inverters, on-grid and hybrid, single and three phase. Our team has repaired 225+ inverters, so we know which settings cause trouble later. SunnyPath Energy is a Partnered AEDB Certified (Category C1) solar EPC company with 550+ systems installed across Pakistan.
Need Zero Export at the Same Time?
If your system has no net metering, or you would rather use every unit yourself, zero export can be set up during commissioning, with a Chint, Eastron or brand smart meter matched to your inverter.
Our Commissioning Checklist
On-Grid and Hybrid Inverter Commissioning
Whatever the brand, every inverter we commission goes through the same checks:
- DC side. String open-circuit voltage, polarity, and the string layout against the inverter’s input limits.
- Safety. Insulation resistance, earthing continuity, and DC and AC breaker and cable sizing.
- Grid settings. The correct grid standard, voltage and frequency protection, and stable firmware.
- Hybrid set-up. Battery type and communication, charge and discharge currents, and backup and work modes.
- Export. Zero export or a fixed export limit with a smart meter, or the settings for net billing.
- Monitoring. Data logger or WiFi connected, and your system added to the brand’s app.
- Testing and handover. The system run under load, and you get the app access and a record of the settings.
Most commissioning jobs take 1 to 2 days, depending on system size. The price depends on the system, so it is quoted once we know the inverter and the set-up. If an inverter is already showing faults, our inverter repair team diagnoses it first.
Commissioned Systems Are Easier to Look After
With the monitoring app connected at commissioning, you can see your generation every day, and so can we if you are on our maintenance plan. Problems show up in the data long before they show up on your bill.
Bought Your Own Inverter?
Plenty of customers buy an inverter themselves and then need someone to install and set it up properly. We commission customer-supplied inverters too, and check the panels, batteries and wiring they connect to, so the whole system works as one.

Frequently asked questions
01What is inverter commissioning?
Inverter commissioning is the set of checks and settings that make a solar inverter run safely and at full output: DC string and insulation checks, earthing, grid settings and firmware, battery and export settings, and connecting the monitoring app, followed by a test under load.
02Which inverter brands does SunnyPath Energy commission?
SunnyPath Energy commissions Huawei, Solis, Growatt, Sungrow, GoodWe, Deye, Fox ESS, Sofar, SAJ, INVT, Chint, Auxsol, Fronius, SMA, Inverex, Knox, Ziewnic, Crown, MaxPower, Fronus, Itel and SolarMax inverters, on-grid and hybrid, single and three phase.
03Can you commission an inverter I bought myself, or one another company installed?
Yes. SunnyPath Energy commissions customer-supplied inverters and systems installed by other companies, and checks the panels, batteries and wiring connected to the inverter as part of the job.
04How long does inverter commissioning take, and what does it cost?
Inverter commissioning usually takes 1 to 2 days, depending on system size. The price depends on the system, so SunnyPath Energy quotes it once it knows the inverter and the set-up.
05Why is my new solar inverter not producing full power?
A new inverter that underperforms is often a commissioning issue rather than a fault: a string layout outside the inverter's input range, the wrong grid settings, an export limit set by mistake, or battery settings limiting output. SunnyPath Energy checks these on site.
06Does commissioning include the monitoring app?
Yes. SunnyPath Energy connects the inverter's data logger or WiFi and adds your system to the brand's app, such as FusionSolar, SolisCloud, ShinePhone or iSolarCloud, so you can see your generation from day one.
07Can zero export be set up during commissioning?
Yes. Zero export, or a fixed export limit, can be set up during commissioning with a Chint, Eastron or brand smart meter matched to your inverter model.
