3-in-1 Space-Saving Power System
Combines 6500W pure sine inverter, 9000W dual MPPT solar charger, and 60A AC grid charger in one 15kg wall-mount unit. Eliminates separate components, complex wiring, and external combiner boxes. Cuts installation time by 60% and frees up valuable wall space – perfect for RVs, tiny homes, and compact utility rooms where every inch counts.<10ms Seamless Backup Transfer
Switches from grid to battery in under 10ms – faster than a single AC cycle. Zero flicker, no device resets, and uninterrupted operation for CPAP machines, medical monitors, servers, and refrigeration. Competitors take 20–50ms, which can reboot sensitive gear. This is medical-grade reliability that keeps critical loads running through any blackout.True Independent Dual MPPT – 99.9% Efficiency
Two fully separate 4500W MPPT channels operate autonomously – shading on one string never affects the other. Delivers 15–25% more annual solar harvest than single-MPPT or shared-bus designs. Ideal for multi-orientation roofs or partially obstructed arrays. Maximize every ray of sun, even in real-world imperfect conditions.Battery-Free Startup + 39kW Scalability
Run solar directly through the inverter to offset grid power immediately – no battery purchase required upfront. Add any 48V LiFePO₄ battery later when ready. Parallel up to 6 units for 39kW total output with no master-slave dependency. Start small, grow big – from a weekend cabin to a full commercial workshop.Smart Auto-Generator & Remote Management
Dry contact port automatically starts a backup generator when battery voltage drops – perfect for unattended off-grid sites. RS485/CAN ports support BMS integration and optional Wi-Fi/4G monitoring for real-time status and historical data. Program charge priorities and time-of-use schedules for true 24/7 automated energy management.
For 15 years, WattCycle has empowered American families and adventurers with safer, smarter energy storage solutions.
