Solar installers are finding growth beyond traditional residential work. New Zealand’s off-grid market brings technical challenges that reward electricians with the right expertise and equipment. The TBB Raython M-Series is factory-assembled, turning complex off-grid installs into straightforward professional projects.
Growing Off-Grid Demand
Remote properties across New Zealand need reliable, autonomous power. Holiday homes in isolated locations, lifestyle blocks beyond economic grid connection, rural businesses, and agricultural operations all require systems that operate independently for extended periods.
Owners in these situations know reliability matters more than upfront cost. Equipment must perform through variable weather, seasonal demand shifts, and equipment cycling—requirements that call for professional-grade components and installation expertise.
Four Systems for Every Off-Grid Application
Raython M5 (5kW, 5.04–20.16kWh) suits smaller off-grid homes, remote holiday properties, and isolated work facilities. The programmable smart port handles generator integration or load management automatically, removing manual switching during power transitions.
Raython M8 (8kW, 10.08–20.16kWh) powers larger remote residences and lifestyle blocks. With 300% surge capacity, it starts heat pumps, workshop equipment, and multiple appliances simultaneously, essential where power interruptions aren’t acceptable.
Raython M10 (10kW, 20.16–40.32kWh) delivers commercial-grade performance for substantial remote properties and off-grid businesses. Dual AC inputs can manage multiple generator sources automatically, ensuring continuous operation even during maintenance windows.
Raython M15 (15kW, 30.24–40.32kWh) provides maximum capacity for demanding applications—large remote properties, commercial facilities, and agricultural operations where reliability directly impacts productivity.
Streamlined Professional Installation
Every Raython system arrives factory-assembled and tested as a complete unit. Solar hybrid inverter, lithium battery modules, E4 monitoring, and power distribution integrate within a single IP54-rated outdoor cabinet. This removes component compatibility issues, reduces commissioning time, and minimises field problems.
Standard electrical connections replace specialised battery and inverter integration knowledge. Crews connect AC and DC wiring using familiar techniques—no specialised training required for basic installation and commissioning.
The transformer-based design handles real-world loads that challenge other systems: motor starting currents, inductive equipment, and power-quality variations common in remote installations. Multiple MPPT trackers maximise solar harvest regardless of panel orientation or shading.
Intelligent Power Management
Power Control monitors loads continuously, adjusting battery charging to prevent generator overload. This keeps generators within optimal efficiency while extending equipment life—crucial where service access is limited.
Power Assist supplements generator output with battery power when loads exceed available capacity. Smaller, more economical generators can handle larger peaks, reducing equipment investment and fuel consumption.
Automatic Generator Start monitors battery levels and initiates backup power when needed, eliminating manual intervention during extended cloudy periods. Essential for unattended properties or installations where owners aren’t technically oriented.
Dual AC inputs (M10/M15) accept multiple generator sources with seamless switching, while separate critical and non-critical outputs enable sophisticated load management during low-power conditions.
Remote System Management
NOVA connectivity provides real-time monitoring via web and mobile apps. Installers can diagnose issues remotely, schedule maintenance proactively, and resolve many problems without site visits—especially valuable in remote locations.
Local E4 displays give owners immediate status feedback: battery levels, solar production, generator operation, and load consumption. This transparency builds confidence and reduces support calls.
Proven Long-Term Reliability
LiFePO4 batteries deliver over 6,000 cycles at 90% depth of discharge, providing decades of service. An operating range from -20°C to 55°C suits New Zealand’s diverse climate without performance degradation.
Five-year warranties extend to ten years, ensuring long-term system security for both installers and customers.
