A Practical Guide from Jeho Ashar Energy 

Your solar inverter is the heart of your solar power system. It converts the DC (direct current) electricity generated by your solar panels into usable AC (alternating current) power for your appliances. So, when the inverter malfunctions, the whole system suffers — sometimes causing partial or total power loss.

At Jeho Ashar Energy Advantage, we help homeowners, estates, and businesses identify and fix inverter faults quickly, so they can enjoy uninterrupted solar power. This article will guide you through:

• How to identify inverter problems

• Common inverter fault signs

• What you can do before calling for help

• When to involve a professional

🔍 What Is a Solar Inverter Supposed to Do?

In a working system, your inverter should:

• Display a green or blue light (status OK)

• Show solar generation during the day

• Charge the battery (if present)

• Supply power to your loads

When it doesn’t do these things, the issue may be in the inverter, panels, wiring, battery, or grid connection (if hybrid).

🚨 Signs Your Solar Inverter Has a Problem

Here are the most common symptoms of inverter failure:

These problems may occur suddenly (e.g. a power surge) or gradually (e.g. worn components).

🛠️ Step-by-Step: What to Do When You Suspect an Inverter Fault

✅ Step 1: Check the Inverter Display

• Look for any error code, warning symbols, or flashing lights.

• Some inverters (like Victron, Deye, Growatt, SMA) show messages like:

  • Grid Fault

  • Battery Low

  • PV Overvoltage

  • Overload

  • No Utility

👉 Write down or take a photo of the error — it’s helpful for your installer.

✅ Step 2: Check Your Circuit Breakers

• Has the AC or DC breaker tripped?

• Is the battery or PV isolator switch off?

• Reset them (if safe) and watch for immediate retripping — a sure sign of an ongoing issue.

✅ Step 3: Check Solar Input (PV) and Battery

• Is it daytime with good sunlight? If not, PV input will be low.

• Are your solar panels dirty or shaded?

• Is the battery voltage critically low (check via app or display)?

Low PV input or flat batteries can stop the inverter from turning on or staying on.

✅ Step 4: Restart the Inverter

• Turn off the inverter and all breakers.

• Wait 30–60 seconds, then restart:

  1. Turn on DC (solar input)

  2. Turn on battery (if available)

  3. Turn on AC output or grid input

  4. Then power on the inverter

This soft reset can often clear minor internal glitches.

⚠️ Step 5: Know When to Call a Professional

If the inverter:

• Shows a persistent error after reset

• Fails to charge even on a sunny day

• Refuses to power on, even with all switches OK

• Shuts down frequently or trips breakers

…then it’s time to contact Jeho Ashar Energy Advantage.
