Solar Input and Battery Flexibility

Dual MPPT trackers manage suitable solar strings to support energy harvesting as conditions change. The supplied 20kW PV input ceiling is an input rating, not a continuous AC output rating. Your installer must confirm string voltage, current and the exact model's solar input limits before connecting panels.

Lead-acid and compatible lithium-ion battery support offers flexibility for energy storage. Configure charging settings and current limits to match the battery manufacturer's requirements. BMS communication compatibility must be verified for the selected lithium battery. The optional external temperature sensor is not stated as included.

Protection and Monitoring

Integrated PV arc-fault detection and output overvoltage protection support system safety. IP65 provides dust and water-jet protection, not immersion protection. Follow manufacturer requirements for installation position, ventilation, earthing and electrical protection. Confirm supported smart monitoring equipment and included accessories before purchase.

Warranty

A 5-year warranty is stated in the supplied product information. Confirm applicable manufacturer or supplier coverage, registration requirements, service arrangements and exclusions before purchase.

Frequently Asked Questions

What makes this inverter suitable for larger solar installations?
Its three-phase hybrid configuration, dual MPPT tracking and up to 20kW PV input support offer solar and battery energy management for suitably designed properties. Load assessment is essential before selection.

Does it support lithium batteries?
Yes, it supports compatible lithium-ion batteries with BMS communication, as well as lead-acid batteries, within the supplied 40–60V battery range. Confirm supported battery models, communication protocols and settings.

Can it work with modern solar panels?
Suitable panels can be used when the array's voltage, operating current and short-circuit current remain within the inverter's model-specific limits. Panel wattage alone does not establish compatibility.

Is it suitable for offices, factories and warehouses?
It can suit appropriately sized three-phase installations. A qualified professional must assess phase loads, motor starting currents, battery capacity and any required backup circuit.

Will it provide battery backup during load shedding?
A correctly configured compatible battery and backup circuit can support selected loads, subject to the model's backup ratings. Runtime depends on usable battery capacity and connected loads; uninterrupted supply is not guaranteed.

Installation Notes

Professional installation is recommended. Verify the exact model datasheet for rated AC output, PV limits, backup capability, battery compatibility and protection requirements before purchase. Grid-connected or net-metering operation requires applicable utility and regulatory approval. Maximum efficiency and current values are rated limits, not guaranteed performance under every operating condition.
