Introduction
A solar inverter is one of the most important components in any solar power system. If you are planning to install solar at home, understanding what a solar inverter is, the different types available, and their prices in Kenya will help you avoid costly mistakes and choose the right system.
What Is a Solar Inverter?
A solar inverter converts electricity generated by solar panels from direct current (DC) into alternating current (AC), which is the type of power used by household appliances.
Without an inverter, solar panels alone cannot power your TV, fridge, lights, or sockets.
Why a Solar Inverter Is Important
- Converts solar power into usable electricity
- Manages battery charging and discharging
- Protects appliances from power surges
- Controls power flow between solar, batteries, and grid
Types of Solar Inverters in Kenya
1. Off-Grid Solar Inverters
Off-grid inverters work independently from KPLC. They rely on solar panels and batteries to supply power.
Best for:
- Rural homes
- Areas without grid electricity
- Homes that want full energy independence
2. Grid-Tied Solar Inverters
Grid-tied inverters work together with KPLC power. They use solar during the day and grid electricity at night.
Important: These inverters shut down during blackouts for safety reasons.
Best for:
- Homes with reliable grid power
- Reducing electricity bills
3. Hybrid Solar Inverters
Hybrid inverters combine solar, batteries, and grid power into one system. They are the most popular choice for Kenyan homes.
Best for:
- Homes experiencing frequent blackouts
- Urban and suburban households
- Future system expansion
Solar Inverter Sizes Explained
Inverter size is measured in kilowatts (kW) and must match your power usage.
- 1–2 kW: Small homes and bedsitters
- 3–5 kW: Medium-sized family homes
- 6–10 kW: Large homes and high-power appliances
Solar Inverter Prices in Kenya (2025/2026)
