Hey, if you’re putting together a serious off-grid or backup power system in Kenya and need something that can handle heavy loads like fridges, pumps, or even air-cons without flinching, the TBB Matrix II 15kVA hybrid inverter is one of those workhorses that locals swear by. This 15 kVA (12 kW continuous) pure sine wave beast uses a proper low-frequency toroidal transformer, so it has massive surge capacity—up to 3x for motors and pumps—and runs super stable even with dodgy loads. It’s fully hybrid, so it prioritises solar, pulls from batteries when needed, and tops up from grid or generator automatically, perfect for Kenya’s unpredictable power situation. Comes with a WiFi dongle for phone monitoring (TBB’s own app), built-in 120A MPPT charger, and you can parallel up to 9 units for huge setups. Rugged steel case, fan-cooled, and designed for hot, dusty environments—many Kenyan installers love it for homes, schools, or small factories because it just keeps going year after year.
Key Features
- Low-Frequency Toroidal Transformer: Real heavy-duty design with 3x surge capacity for starting big motors, compressors, or pumps without tripping—way tougher than high-frequency inverters.
- Pure Hybrid Operation: Smart energy management prioritises solar → battery dump → grid/generator, with seamless transfer and programmable charge profiles for lithium or lead-acid batteries.
- High-Capacity MPPT Charger: Built-in 120A solar charger (up to 6000W PV input) with wide voltage range for flexible panel layouts in Kenyan sun.
- WiFi Monitoring Included: Plug-in dongle gives full remote control and monitoring via TBB app—check power flow, set timers, or get alerts from anywhere in Kenya.
- Parallel & Three-Phase Ready: Up to 9 units in parallel (single or 3-phase), so you can scale to 135 kVA if your project grows.
- Rugged Build for Kenya: Steel enclosure, advanced cooling, works in high heat/dust, with comprehensive protections (overload, short-circuit, over-temp, low battery, etc.).
