Your Inverter May Explode Soon If You Ignore This Simple Rule

ByGLOBALNET ICT

Yes — explode.
It sounds dramatic, but thousands of Nigerians unknowingly damage their inverters every single day because of one simple mistake installers rarely talk about.

The worst part?
This mistake is 100% preventable… if you size your solar system correctly.

Before we get into the “explosion rule”, let’s start with why it happens.

The Real Danger: Wrong Sizing = Overloading

Most inverters don’t fail because they’re “bad quality.”
They fail because they’re forced to carry loads they were never sized to handle.

And once an inverter is overloaded:

  • internal components overheat,
  • MOSFETs crack or burn,
  • capacitors blow,
  • wires melt,
  • sparks fly…
    …and yes, the inverter can explode or catch fire.

This is why proper solar sizing is the foundation of a safe solar installation.

Here’s the Simple Rule Installers Don’t Tell You

👉 NEVER guess your inverter size. Always calculate your load properly.

That’s the rule.
Sounds simple, but 80% of people ignore it — and pay for it later.

Most Nigerians buy an inverter based on:

  • “What my neighbour bought”
  • “The one the installer recommended”
  • “The one my budget can carry”

But electronics don’t care about your neighbour or your budget.
If the load is too much, the inverter will fail — violently.

How to Calculate Your Load (The Correct Way)

Your total load = sum of all appliances × their running watts

Example:

  • 1 TV — 70W
  • 4 bulbs — 10W each = 40W
  • 1 fan — 60W
  • 1 decoder — 20W
  • Phone chargers — 20W

Total load = 70 + 40 + 60 + 20 + 20 = 210W

If you plan to add a freezer later, size for it NOW. Never size exactly to your current load.

This is exactly where the Globisun App becomes your best friend.

You can instantly calculate your solar needs, including:

  • inverter size
  • battery capacity
  • solar panels
  • and safe cable sizes

…without any guesswork.

Why Load Miscalculation Causes Inverter Explosion

1. The inverter overheats

Electrical components generate heat under strain.
Too much heat → internal short circuits.

2. Voltage drops spike the system

Overloading creates unstable voltage, frying the inverter.

3. Internal components melt or burst

If the inverter’s protection fails, the damage becomes explosive.

4. Battery stress adds extra danger

Wrong battery sizing pushes the inverter harder, doubling the risk.

All these issues come from the same root problem:
wrong system sizing.

You can avoid all of them using a proper solar system design calculator.

How to Size Your Inverter the Right Way

Here’s the rule of thumb:

Inverter Size = Total Load (Watts) ÷ Power Factor + 20% safety margin

Most homes use a power factor of 0.8.

Example:
Your load = 800W

Inverter size:

800 ÷ 0.8 = 1000W
Add 20% = 1200W minimum

So you need a 1.2kVA to 1.5kVA inverter — NOT a 1kVA.

Again, this can be done instantly inside the Globisun App using the load calculation tool.

Signs Your Inverter Is About to Fail

If you notice any of these, STOP using it immediately:

  • inverter feels unusually hot
  • humming or buzzing noise increases
  • plastic smell or burning smell
  • inverter shuts down unexpectedly
  • battery drains faster than normal
  • cables heat up

These are warning signs of overload stress.

Fix the root cause — wrong sizing — before the system fails completely.

The Easy Way to Prevent Inverter Explosion

Instead of:

❌ calculating with pen and paper
❌ relying on your installer’s word
❌ guessing your load
❌ using trial and error

Just use a proper mobile tool designed specifically for Nigerian solar users.

The Globisun Solar App helps you:

  • size your inverter correctly
  • compute battery bank requirements
  • calculate solar panels needed
  • choose correct cable sizes
  • get daily solar weather forecast
  • and design your entire solar system in minutes

This is the only way to avoid overload-related inverter failures.

Final Thoughts — Your Safety Depends on Proper Sizing

Your inverter won’t just suddenly explode.
It fails slowly… then violently… after months of carrying a load it wasn’t designed for.

You can prevent that today.

Take 30 seconds to size your system correctly using the Globisun App.
