Whole Home Bypass

The Wirentech 12kW hybrid inverter combines 120/240V split-phase output with a separate 200A grid-bypass path for whole-home panel integration on a 51.2V battery platform.

Large Load Planning

Plan compatible whole-home, central HVAC, well, water, EV, and other 240V loads by voltage, running watts, and starting surge while recognizing that 200A applies to grid pass-through rather than battery-mode output.

Dual MPPT Solar

Two MPPT groups support up to 12kW plus 12kW of documented PV input with a 90–450V tracking range, 500V maximum VOC, 160A maximum AC charging, and 250A maximum PV charging.

Grid Bypass Explained

Solar, grid, generator, and battery paths provide flexible energy recovery, while the 200A rating describes grid power passing through the enclosure and does not increase the 12kW battery-mode output or runtime.

Output Bypass Performance

The inverter provides 12kW continuous output, 18kVA peak power, 10ms typical transfer, motor-starting capability up to 6HP, a 7.2kW single-phase limit, and a separate 200A grid-bypass path.

Battery Current Matching

Size a capable 51.2V battery bank for the documented 40–58.6Vdc operating range and 44V minimum start voltage, with 160A maximum AC charging, 250A maximum PV charging, and USB plus RS485 communication.

Integrated Electrical Protection

Manual-documented safeguards address overload, short circuit, PV reverse polarity, AC reverse conditions, overvoltage, and temperature while still requiring correctly sized external protection, wiring, grounding, and installation.

Parallel Suffix Requirements

Parallel operation is limited to the documented -500P_PLUS suffix for configurations of up to six units; the -500_PLUS version must not be assumed to support parallel operation.

Professional Installation Planning

The heavy-duty enclosure measures 710 × 485 × 145 mm, weighs 37.5 kg or 82.7 lb, operates from -10°C to 55°C, and requires professional service-panel design, wall support, airflow, protection, wiring, and commissioning.

FAQs

What is included with the inverter?

This product describes one Wirentech 12kW 120/240V split-phase hybrid inverter with an integrated 200A grid-bypass enclosure. Batteries, solar panels, generator equipment, external breakers, disconnects, cables, and other system components are not included unless the exact product listing states otherwise. Confirm the complete model suffix and included accessories before ordering.

What does the 200A bypass rating mean?

The 200A rating applies to the grid pass-through path inside the bypass-equipped enclosure. It allows grid power to pass through the inverter enclosure to backed-up loads when the system is configured accordingly. It does not mean the battery inverter can deliver 200A in backup mode, and it does not increase battery capacity or outage runtime.

Can it support both 120V and 240V loads?

Yes. The inverter provides 120/240V split-phase output for compatible whole-home circuits, HVAC equipment, water systems, EV charging, and other selected loads. Battery-mode continuous output remains 12kW, while loading assigned to a single phase is limited to 7.2kW. Plan phase balance and simultaneous demand with a qualified installer.

How much continuous and peak power does it provide?

The inverter provides 12kW of continuous battery-mode output and up to 18kVA of peak power, with 10ms typical transfer and motor-starting capability up to 6HP under the specified conditions. Verify the running watts and starting surge of every connected appliance or motor. The 200A bypass rating is separate from these output limits.

What solar input does the inverter support?

The documented Plus configuration uses two MPPT groups supporting up to 12kW each, or 24kW total PV input, with a 90–450V MPPT range and 500V maximum open-circuit voltage. Maximum charging is listed as 160A from AC and 250A from PV. These are electrical limits, not promised solar production or recharge times.

Can it use solar, grid, generator, and battery power?

Yes. The hybrid platform can coordinate solar input, grid or bypass power, generator charging, and battery storage for solar self-use, scheduled charging, outage reserve, and multiple recovery paths. Final source configuration, transfer logic, and charging settings must follow the exact inverter manual and applicable electrical codes.

Which battery platform should be used?

The inverter is designed around a 51.2V nominal battery platform with a documented 40–58.6Vdc operating range and 44V minimum start voltage. The battery bank must be sized for the inverter's continuous current and motor-start surge rather than the 200A bypass rating. Confirm battery current capability, BMS protocol, and charging settings before connection. USB and RS485 communication are supported.

What protection functions does the inverter provide?

Manual-documented safeguards address overload, short circuit, PV reverse polarity, AC reverse conditions, overvoltage, and temperature across the grid, PV, and battery paths. These internal functions do not replace correctly sized breakers, fuses, disconnects, conductors, grounding, ventilation, or professional installation.

Can multiple bypass inverters operate in parallel?

Parallel operation applies only to the documented -500P_PLUS suffix, with configurations of up to six units. The -500_PLUS version must not be assumed to support parallel operation. Verify the complete model number, parallel accessories, bypass integration, communication requirements, and installation instructions before ordering or commissioning.

What should I verify before installation?

Verify the service-panel and bypass design, split-phase load plan, phase balance, battery current capability, PV configuration, generator connection, model suffix, conductor sizes, protection devices, airflow, and wall support. The enclosure measures 710 × 485 × 145 mm, weighs 37.5 kg or 82.7 lb, and has a listed operating range of -10°C to 55°C. A 5-year limited inverter warranty applies under its terms.
