Solar Installation in Opete Warri: 4kVA 24V System Running AC, Fridge & Full House (Technical Breakdown)



🔎 STEP 1: Proper Load Calculation (Most Installers Skip This)
Appliances involved:
1 AC (daytime use mainly)
Refrigerator
TV
CCTV system
10+ bulbs
Multiple fans
Phones & laptops charging
Estimated Load Breakdown
AC: ~1,200–1,500W (startup surge higher)
Fridge: ~150–250W (with surge)
TV + CCTV: ~200W
Bulbs: ~150W
Fans: ~200W
Misc charging: ~150W
Daytime working load average: ~2,000–2,500W
Peak surge (when AC + fridge kick in): 4,000W+
This is where engineering thinking starts.

⚙️ STEP 2: Why We Chose a 4kVA 24V Gospower (100A MPPT)
We installed:
Inverter: 4kVA / 24V Gospower (built-in 100A MPPT)
Why not 3kVA? Because surge matters more than average load.
AC compressors and refrigerators don’t care about your inverter rating — they pull what they need on startup.
A 4kVA inverter gives:
Better surge handling
More headroom
Less stress on components
Longer lifespan
About the 100A MPPT
At 24V system: 100A MPPT × 24V ≈ 2,400W solar charging capacity (theoretical charging side)
This ensures:
Faster battery charging
Better harvesting even under partial cloud (common in Delta afternoons)
MPPT (Maximum Power Point Tracking) is critical here — it extracts maximum usable power from the panels instead of wasting voltage like PWM controllers do.

🔋 STEP 3: Battery Bank Engineering
We used:
2 pcs 5kWh / 24V 200Ah batteries connected in parallel
Parallel connection keeps voltage at 24V but doubles capacity.
So:
24V system
400Ah total capacity
Energy storage ≈ 9.6kWh usable (depending on depth of discharge settings)
Why this size?
Client wanted:
Stable night power (no AC overnight)
Fridge, fans, TV, CCTV till morning
Night load estimated around: ~800–1,200W average
With proper battery management, this comfortably runs through the night without deep discharging — which is what kills batteries in many Warri installations.

☀️ STEP 4: Panel Sizing (12 × 450W Panels)
Total panel capacity: 450W × 12 = 5,400W (5.4kW)
Why 5.4kW?
Because in Delta State:
Heat reduces panel efficiency
Dust reduces output
Clouds reduce harvest
And real-world output is rarely nameplate rating
So we oversize panels slightly to ensure:
Batteries charge fully before 2–3pm
AC can run during the day directly from solar
Excess energy tops batteries
➕ Additional 60A Cworth MPPT Controller
Because of panel arrangement and roof layout limitations, we added:
60A Cworth MPPT charge controller for additional panel strings.
Why?
Instead of forcing all panels through one controller and risking imbalance or underutilization, separating arrays:
Improves harvest efficiency
Reduces MPPT stress
Provides redundancy
Allows better voltage configuration
This is something many installers ignore.
They focus on “how many panels” — not “how efficiently they’re managed.”
🧱 Special Challenge: Roof Space + Surge Planning
Roof space wasn’t perfectly aligned.
We had to:
Split panel orientation carefully
Ensure string voltage stayed within MPPT limits
Balance shading risks
Also, AC startup surge was a concern.
So wiring gauge, DC protection, and breaker sizing were carefully selected to prevent voltage drop — which is a silent killer of 24V systems.


❌ Common Mistakes I See in Similar Installations in Warri

Installing 3kVA inverter for AC load
Using only 2–4 panels and expecting miracles
Undersized batteries that die in 6 months
No proper surge planning
Poor cable sizing
No DC breakers or SPD protection
Wrong battery parallel configuration


Solar doesn’t fail. Poor engineering fails.
