Introduction

Many Nigerian homes and offices want to enjoy AC on solar — but not all solar systems can support air conditioners.

If your AC:
❌ refuses to start,
❌ trips the inverter,
❌ makes the inverter beep,
❌ runs for a few minutes then shuts down,
or
❌ drains your battery immediately,

then there is a problem with your system design, not the AC itself.

In this guide, Solarzone Nigeria explains exactly why your solar system is not powering your AC and what to do to fix it permanently.

⭐ 1️⃣ Your Inverter Is Not Strong Enough to Carry AC

Air conditioners require higher startup (surge) power than their running load.

❌ Example:

• 1HP AC = 750W running

• But surge = 2,000W – 3,000W
  If your inverter is small, it will TRIP.

✔ Minimum inverter sizes for AC:

• 1HP AC → 5kVA–7.5kVA inverter

• 1.5HP AC → 7.5kVA–10kVA inverter

• 2HP AC → 10kVA–15kVA inverter

If you use anything lower, the AC won’t work reliably.

⭐ 2️⃣ Your Battery Is Too Weak for AC Loads

ACs require strong, stable battery power.

Weak batteries cause:
❌ inverter tripping
❌ low voltage
❌ AC not starting
❌ short backup

✔ Solution:

• upgrade to lithium batteries

• increase Ah capacity

• replace old tubular batteries

📌 Tubular batteries are NOT ideal for AC — they drain too fast.
Lithium is the correct battery type for AC usage.

⭐ 3️⃣ You Don’t Have Enough Solar Panels

If solar panels are too few:
❌ AC runs directly on battery
❌ system drains fast
❌ inverter overloads
❌ batteries die faster

✔ Minimum panel requirements for AC:

• 1HP AC → 6–10 panels

• 1.5HP AC → 10–16 panels

• 2HP AC → 16–24 panels

To run AC during the day, panels must supply enough power so battery is not heavily used.

⭐ 4️⃣ Your Solar System Was Not Designed for AC Use

Many installers build systems ONLY for:
✔ TV
✔ lights
✔ fans
✔ freezer

Not AC.

AC loads require:

• correct wiring

• inverter with high surge capability

• proper MPPT rating

• strong battery bank

Solarzone designs systems specifically for AC loads — not guesswork.

⭐ 5️⃣ Wrong Type of AC Installed

❌ Problem:

Local non-inverter ACs have very high surge current.

✔ Solution:

Use Inverter ACs for solar systems:
✔ lower power consumption
✔ smooth startup
✔ minimal surge
✔ runs longer on battery
✔ deeper night backup

If you’re using a non-inverter AC, your inverter will struggle.

⭐ 6️⃣ Wrong or Poor Wiring

Thin or long-distance wires cause:
❌ voltage drop
❌ overheating
❌ inverter tripping
❌ AC struggling to start

✔ Fix:

Use:

• 10mm or 16mm for battery/inverter

• correct AC wiring size

• short cable runs where possible

Solarzone corrects all wiring faults.

⭐ 7️⃣ Faulty or Inadequate MPPT / Charge Controller

Your MPPT might be:
❌ too small
❌ weak
❌ faulty

If it cannot push enough current, batteries won’t charge well → AC fails.

✔ Fix:

Upgrade MPPT to:

• 60A

• 80A

• 100A

depending on your solar panel quantity.

⭐ 8️⃣ Overloading the Inverter with Other Appliances

If AC is ON and you’re running:

• freezer

• washing machine

• pumping machine

• microwave

the inverter will TRIP immediately.

✔ Fix:

Create AC-only time periods.
Or upgrade inverter capacity.

⭐ 9️⃣ Battery Voltage Drops Too Quickly

If your voltage drops from:
💧 54V → 48V within minutes (for 48V system)
then AC cannot continue.

✔ Fix:

• install larger lithium battery bank

• add more solar panels

• reduce nighttime AC usage

⭐ 🔟 PHCN or Generator Backfeed Damage

If your wiring setup is wrong:

• AC may refuse to power on solar

• inverter will trip fast

• internal components may burn

This is why professional installation is VERY important.

Solarzone corrects backfeed wiring and protects your inverter.

🏁 Final Thoughts

Your solar system is not powering your AC because of:
✔ small inverter
✔ weak batteries
✔ low panel count
✔ wrong AC type
✔ bad wiring
✔ poor configuration

But the good news is:
AC can run perfectly on solar when the system is designed correctly.

Solarzone builds strong, stable, long-lasting solar systems that power AC without stress.
