Introduction

Solar freezers and fridges are extremely important for homes, stores, restaurants, and businesses in Nigeria.
But many users experience issues like:

❌ freezer not getting cold
❌ fridge switching off on solar
❌ inverter tripping
❌ freezer working only when PHCN is ON
❌ battery draining quickly
❌ compressor not starting

These problems indicate your solar system is not providing enough power.

In this guide, Solarzone Nigeria explains the major reasons your solar freezer or fridge isn’t getting enough power — and how to fix it permanently.

⭐ 1️⃣ Your Inverter Is Not Strong Enough for the Freezer

Freezers require high startup current (surge) even if they have low running watts.

❌ Example:

• 150W freezer

• but surge = 800W – 1500W

If inverter cannot handle the surge:

• freezer won’t start

• inverter trips or beeps

• freezer works only when PHCN is ON

✔ Fix:

Use 5kVA–10kVA inverters for freezers.
Higher surges need bigger inverters.

Solarzone installs AC & freezer-ready hybrid inverters.

⭐ 2️⃣ Weak or Old Batteries

Freezers require stable voltage.

Weak or draining batteries cause:
❌ inverter tripping
❌ compressor stopping frequently
❌ freezer not cooling
❌ fast battery drain

✔ Fix:

• upgrade to lithium battery

• increase battery capacity

• replace old batteries

Tubular batteries perform poorly under freezer loads.

⭐ 3️⃣ Not Enough Solar Panels Installed

If your panels are too few:

• freezer runs directly on battery

• battery drains quickly

• inverter struggles

• system becomes unstable

Freezers require strong daytime solar support.

✔ Minimum panel recommendations:

• Single freezer = 6–10 panels

• Freezer + fridge = 10–16 panels

• 2–3 freezers (business use) = 16–24 panels

More panels = better cooling.

⭐ 4️⃣ Wrong Type of Freezer (Non-Inverter Models)

Non-inverter freezers consume high power.

They produce:

• strong surges

• high watt usage

• heavy strain on batteries

✔ Fix:

Use inverter freezers, which:
✔ consume less
✔ run smoothly
✔ have soft-start compressors
✔ last longer on solar

Solarzone helps select the right freezer for solar use.

⭐ 5️⃣ Freezer Compressor Starting Too Frequently

If the compressor starts:

• every 2–5 minutes

• instead of every 15–30 minutes

It means:
❌ poor ventilation
❌ weak batteries
❌ low power
❌ faulty thermostat

Frequent startup = high power usage.

✔ Fix:

• place freezer in cool, ventilated area

• clean condenser coil

• check thermostat settings

• improve solar & battery capacity

⭐ 6️⃣ Loose or Weak Wiring

Thin or loose wiring causes:
❌ voltage drop
❌ slow cooling
❌ inverter outages

✔ Fix:

Use:

• 10mm or 16mm battery cable

• short wiring distances

• thick AC wires

Solarzone corrects wiring issues.

⭐ 7️⃣ Dirty Solar Panels Reducing Charging

If your battery doesn’t fully charge:

• freezer won’t run at night

• compressor will stop

• battery drains fast

✔ Fix:

• clean panels regularly

• remove shading

• adjust panel angle

Dirty panels = weak power supply.

⭐ 8️⃣ Faulty MPPT/Charge Controller

A weak or faulty MPPT causes:
❌ low charging
❌ battery undercharging
❌ inverter beeping
❌ night freezer shutdown

✔ Fix:

Upgrade MPPT to:

• 60A

• 80A

• 100A

Solarzone supplies high-quality MPPT controllers.

⭐ 9️⃣ Too Many Appliances Running on Solar

If you are running:

• TV

• lights

• fans

• freezer

• pumping machine

• AC

• pressing iron

all at once, the freezer will suffer.

✔ Fix:

Prioritize your freezer or upgrade the system.

⭐ 🔟 Freezer Starting at Night When Solar is Weak

Freezers perform best during the day when solar is strong.

If they start at night:

• massive surge hits battery

• voltage drops

• inverter can trip

✔ Fix:

• ensure freezer cools properly during the day

• increase battery capacity

• make sure daytime charging is strong
