When going solar in Nigeria, one of the most common questions people ask is:
What size inverter do I need for my home or shop?

Choosing the right inverter size is essential for stable power supply, optimal performance, and long-term savings—especially for homes with large appliances or small commercial operations.

Step 1: Know Your Power Consumption

List out your typical appliances and their estimated wattage:

Appliance	Estimated Power (W)
Refrigerator	150
Ceiling Fan	75
LED Lights	10 × quantity
Air Conditioner	1000
Water Pump	750–1000
Microwave	1200

Add up the total. Your inverter’s rated power should be at least 20–30% higher than this number to allow for surge loads and future expansion.

Step 2: Choose Single-Phase or Three-Phase

A：When to Choose Single-Phase

• Small homes with lighting, fans, basic appliances
• Load demand under 6kW
• No three-phase input available

B：When to Choose Three-Phase

• Larger homes or villas with multiple ACs and pumps
• Small businesses, farms, or cold storage units
• Sites with existing three-phase grid or balanced load needs

LuxpowerTek’s TriP2-LB-3P Series is specially built for Nigerian users needing 3-phase output, 48V battery compatibility, and high power flexibility.

TriP2-LB-3P 15–20K	15–20kW	48V lithium/lead-acid	3	Yes	Ideal for larger homes and small industry

Step 3: Plan for Future Growth

① When in doubt, choose a slightly larger inverter (e.g):

If your current load is 5kW, go for a 6kW inverter.

② Want to add batteries later?

Choose a hybrid inverter model now.

③ Planning for business expansion?

Select a parallel-capable model.

Luxpower inverters support future upgrades with features like parallel operation, smart load output, and remote configuration via LuxCloud.

Quick Guide:

For homes: 3–6kW single-phase (GEN2-LB-EU series)

For larger homes or small business: 10–20kW three-phase (TriP2-LB-3P series)
