High-Capacity Backup Power Without a Low-Current Bypass Bottleneck
  • Built-In 200A 2-Pole Bypass: Support high-current 120/240V split-phase systems without forcing grid-supplied loads through a lower-current bypass path. The 200A bypass design is built for homes and properties with higher electrical demands.
  • 12kW Split-Phase Backup Power: Power both 120V and 240V loads from a single inverter. With 12kW of continuous output, 18kVA peak power and rated motor capability up to 6HP, the system is designed for compatible air conditioners, pumps, compressors, refrigerators, lighting and workshop equipment.
  • 24kW Dual-MPPT Solar Input: Connect up to 24kW of solar through two independent 12kW MPPT channels. Each MPPT supports up to 32A input, providing greater flexibility for larger arrays, multiple roof orientations and changing solar conditions.
  • Up to 250A Hybrid Charging: Combine AC and solar charging for up to 250A of total charging current—approximately 12.8kW at a 51.2V nominal battery voltage. Recharge large battery banks faster and reduce the amount of time spent relying on utility or generator power.
  • Generator, Smart Load and AC-Coupling Support: A dedicated generator input, dry-contact control, scheduled charging and programmable smart-load output provide more control over how energy is generated, stored and used. The smart-load interface can also be configured as an AC-coupled input for compatible equipment.
  • Integrated Solar and Electrical Protection: Built-in AFCI detection, photovoltaic rapid shutdown support, insulation-resistance monitoring, overload protection, short-circuit protection and reverse-polarity protection help safeguard the inverter, solar array, battery bank and connected loads.
  • Expandable Up to 72kW: Parallel up to six inverter units for a combined power capacity of up to 72kW. CAN, RS485, USB and Wi-Fi communication support flexible local and remote system monitoring and control.
  • *The 200A rating refers to the built-in AC bypass path. Battery-powered inverter output is rated at 12kW continuous and 18kVA peak.

12kW Backup Power. 200A Grid Pass-Through. 24kW Solar Input.

The WattCycle 48V 12kW Split-Phase Off-Grid Inverter Charger is designed for high-demand home backup, off-grid properties, farms and workshops. It combines a built-in 200A 2-pole grid bypass, 12kW continuous 120/240V split-phase output, 24kW dual-MPPT solar input and up to 250A hybrid charging in one expandable 48V power system.

Unlike many conventional 12kW off-grid inverters that limit utility pass-through through a 63A or 100A bypass path, WattCycle supports a substantially higher-capacity AC bypass circuit while grid power is available. When an outage occurs, the inverter switches to battery power in approximately 10 milliseconds and delivers 12,000W of continuous pure sine wave output with up to 18kVA peak power.
