Preventive Measures You Can Take to Maintain Your Inverter and Prevent Damage
Inverter systems are the heart of most off-grid and backup power solutions, and like every essential device, they require proper care. While the use of protective devices such as surge protectors, circuit breakers, and isolators are commonly recommended (and rightly so), there are additional practical steps every user — even non-technical ones — can take to prevent common inverter faults.
It’s important to note that not all inverter faults are caused by external issues like lightning strikes, voltage surges, or short circuits. Some problems arise from poor installation practices, overheating, battery issues, and neglect in routine maintenance.
Today, we want to share two key preventive actions you can take to keep your inverter running optimally and to avoid two common inverter faults:
Error 02 ( over temperature)
* Dead-set ( Inverter not coming up at all).
1. Preventing Error 02 – Over Temperature Fault
This error usually occurs when the inverter is overheating due to poor ventilation, dust accumulation, or operating under high load conditions.
🔹 Why Cleaning Matters
– Dust buildup blocks air vents, causing overheating.
– Dust can settle inside the fan and slow it down or stop it.
– It can lead to short circuits if it enters internal parts.
– A dirty inverter runs hotter, stressing internal components and batteries.

🔹 How to Clean Your Inverter Safely
Tools You’ll Need:
– A dry microfiber cloth
– A soft paintbrush or small blower
– Optional: Can of compressed air for hard-to-reach areas

🔸 Step-by-Step Cleaning Guide
1. Turn off the inverter and unplug it from the wall (if applicable).
2. Let it cool down before cleaning (especially after a power outage).
3. Gently wipe the surface of the inverter with the dry cloth — clean the screen/display, sides, and top.
4. Use a paintbrush or soft blower to clean:
– Fan vents
– Heat sinks (if exposed)
– Cable connection points (lightly)
5. Avoid spraying any liquid cleaner — never use water or wet cloths.
6. If you’re comfortable, gently blow air into the ventilation grilles using a compressed air can (do not open the inverter)
🔹 How Often Should You Clean?
– Monthly: Surface dusting and fan vents.
– Quarterly: Deeper dry-cleaning (especially in dusty environments).
⚠️ What to Avoid
– Don’t use wet wipes, alcohol, or detergents.
– Never insert sharp objects to remove dirt inside.
– Avoid cleaning while the inverter is ON or connected to AC power.
🏠 Pro Tip:
If your home is dusty or close to roadside areas, consider placing the inverter inside a ventilated cabinet (not airtight) with mesh dust filters.
DEAD-SET INVERTER NOT COMING UP AT ALL.
When an inverter isn’t powering on at all (no lights, no display, no output), the fault is generally referred to as a:
“Dead Inverter” or “No Power Fault”
It can be caused by several possible issues:
But they are 2 major issues that leads to that
Firstly the inverter is that the inverter is being used in a strenuous condition where DC input which means battery voltage is poor or batteries not in good condition.
There are mainly 3 types of battery being used in the Nigerian market for.
They are
- Lithium batteries
- Dry cell batteries.
- Lead acid battery, Tubular batteries.
If you are making use of the Lithium batteries ( either LP04 or Lithium battery) you will not worry about this, because such battery comes with a battery management system that keeps the cells in check and sometimes they communicate with the inverter helping a seamless management of the battery life from the battery to the inverter.
But if you are using the Lead Acid battery.
The efficiency of this battery is usually rated between the life span of 3 to 5 years, but when you begin to notice a drastic reduction in the back up time. You should begin to consider replacing the batteries to prevent this fault, because if the cells in the battery can no longer deliver the necessary power needed for the inverter to function efficiently the inverter module will begin to work at an extensive strenuous condition which could abruptly lead to the damage of the inverter.
But my major focus is for people using the Lead Acid battery ( Tubular batteries).
This is a widely used battery among many backup setups in Nigeria, and while the battery meets the needs of many end users poor maintenance of the battery can lead to damage of the inverter unit.
These types of batteries make use of acid+distilled water to keep the electrolytes and the cells in it active and efficient for delivering back up power, and when they are being used over some time the liquid solution inside begins to drop because they evaporate when being used.
Poor maintenance or proactive procedures can also cause ( Dead Set on an inverter).

Great — let’s break down Measure 2: Monitor Battery Water Level (for Tubular or Flooded Batteries) extensively.
✅ 2. Monitoring Battery Water Level
If you’re using tubular lead-acid (wet-cell) batteries (commonly used with many inverters in Nigeria), monitoring and maintaining the electrolyte level is critical for battery health and performance.
🔹 Why It’s Important:
– These batteries contain liquid electrolyte (a mixture of distilled water and sulfuric acid).
– During charging and discharging, water evaporates gradually.
– If the water level drops too low, the lead plates get exposed, leading to:
– Permanent damage
– Reduced backup time
– Overheating
– Shorter battery lifespan
🔸 How to Check Battery Water Level
Tools You’ll Need:
– A flashlight (to see inside battery caps)
– A distilled water bottle
– Protective gloves and eyewear (recommended)
🔸 Step-by-Step Guide
1. Turn off the inverter and disconnect from power.
2. Open the battery cover (if any) to access the individual battery caps (usually 6 per battery).
3. Open each cap carefully.
4. Use a flashlight to look inside the opening. You should see the water level above the plates.
5. If the plates are visible, the water is too low.
6. 6. Top it off only with distilled water until it reaches the recommended level (usually just below the vent hole).
7. Close the caps tightly after filling.
⚠️ NEVER DO THE FOLLOWING:
– Never add tap water or battery acid — only pure distilled water.
– Don’t overfill — it can cause overflow and corrosion.
– Don’t open the caps while charging — wait until the battery is cool.
🔹 How Often Should You Check?
– Monthly if you use the inverter regularly.
– Every 2 weeks during hot seasons (more evaporation).
– If the battery backup suddenly drops, check immediately.

🧪 Pro Tip:
Label your batteries and track the last date you checked or refilled water. This helps avoid neglect.
Secondly, the reason that can lead to a Dead Set in an inverter is if it comes in contact with liquid.
Well some modern types of inverters are built to be used in all terrain while others aren’t.
You must ensure your inverter is installed in a cool and dry place free from contacting any form of liquid, because inverter modules aren’t friendly with liquid substances.
Conclusion:
Maintaining your inverter system doesn’t always require advanced technical skills. With simple but consistent preventive measures — like ensuring proper ventilation to avoid overheating, and keeping the system clean and dry to prevent internal faults — you can greatly extend the life of your inverter. While protective devices play a key role, user habits and awareness also make a huge difference. Taking small steps regularly can save you from costly repairs and unexpected power disruptions. Prevention is not just better than cure — it’s cheaper, easier, and smarter.
