Introduction

As your home grows, your electricity demand grows with it.
More appliances, more devices, more comfort needs — all of which can put extra pressure on your solar system.

If your inverter suddenly backs up less than before, charges slowly, or struggles with new appliances, it may be time for an upgrade.

In this guide, Solarzone Nigeria explains the clear signs that tell you your solar system needs expansion or upgrade — plus what to upgrade and how to do it correctly.

⭐ 1️⃣ Your Backup Time Has Reduced

If your solar system used to last all night but now drains quickly, it’s a clear sign that:

✔ Your batteries are aging
✔ Your solar panels are too few
✔ Your load has increased
✔ Your inverter is overworked

Solution:

• Add more solar panels

• Upgrade from tubular to lithium

• Rebalance your load

• Install additional batteries

Solarzone performs battery health tests to confirm the cause.

⭐ 2️⃣ You Added New Appliances

New appliances like:

• Freezer

• TV

• Fans

• Pump

• AC

• Washing machine

…increase your power demand.

If your system was not sized for these appliances, backup time will reduce.

Solution:

✔ Add more panels
✔ Increase inverter size
✔ Add lithium battery

Solarzone custom-sizes your system to match your new power needs.

⭐ 3️⃣ Your Solar Panels No Longer Charge Fast

If your batteries are not hitting 100% before evening, something is wrong.

Causes:
❌ Insufficient solar panels
❌ Dusty panels
❌ Weak MPPT/PWM controller
❌ Old installation design

Solution:

✔ Upgrade from PWM to MPPT
✔ Upgrade from 2–4 panels to 6–10 panels
✔ Adjust panel angle
✔ Replace aged panels

Solarzone upgrades charging systems for faster performance.

⭐ 4️⃣ Your Batteries Are Getting Weak

After some years, all batteries begin to lose capacity.

Signs:

• Backup time drops

• Inverter trips early

• Battery voltage fluctuates

• Battery doesn’t hold charge

Solution:

✔ Replace tubular with lithium
✔ Add extra batteries
✔ Reconfigure charging settings

Solarzone offers Felicity, Dyness, and Blue Carbon lithium batteries.

⭐ 5️⃣ Your Inverter Begins to Overload or Trip

If your inverter shuts down when you use:

• Pump

• Pressing iron

• Freezer

• AC

• Microwave

• Multiple fans

…it is too small for your current load.

Solution:

✔ Upgrade to 3.5kVA, 5kVA, 7.5kVA or above
✔ Install pure sine wave hybrid inverters
✔ Rebalance load between circuits

Solarzone installs high-efficiency Felicity hybrid inverters.

⭐ 6️⃣ Your Electricity Bill Suddenly Increases

If your PHCN units are finishing faster, it means:

❌ Your solar is charging less
❌ Your inverter is taking power from PHCN
❌ Your batteries are weak
❌ Your panels are insufficient

Solution:

✔ Increase panels
✔ Add lithium battery
✔ Fix inverter priority settings

Proper solar upgrades reduce electricity cost by 40–70%.

⭐ 7️⃣ Rainy Season Affects Your Charging

If your solar system struggles during rainy season, that's a major sign you need:

✔ Additional panels
✔ MPPT controller
✔ Lithium battery
✔ Higher panel wattage

Solarzone upgrades systems for cloudy-weather performance.

⭐ 8️⃣ Your Family or Business Has Grown

More people = more usage.

Examples:

• New baby (fans, sterilizers, fridge use increases)

• New staff in an office

• Business expansion

• Increased night load

Solution:

✔ Upgrade inverter
✔ Add panels
✔ Add batteries
✔ Rewire for load balance

Solarzone performs usage audits to calculate new requirements.

⭐ 9️⃣ You Want to Start Running Your AC on Solar

Running AC on solar is possible but requires:

✔ Enough panels
✔ Lithium battery
✔ High-power inverter
✔ Correct wiring
✔ Proper design

If your current system can’t handle AC, it’s time to upgrade.

Solarzone designs AC-compatible solar systems.

⭐ 🔟 You Want to Achieve 24/7 Solar-Powered Living

If you want:

• Zero generator

• Zero PHCN reliance

• Constant power

• Complete solar independence

…then an upgrade is necessary.

This often includes:
