Solar Generation and Energy Storage

Dual MPPT tracking supports solar energy harvesting from suitably configured strings as operating conditions change. The 18kW PV rating is separate from the 12kW output rating and does not indicate 18kW continuous AC output. Panel voltage, current and string layout must remain within the exact model's limits.

Lead-acid and compatible lithium-ion battery support gives you storage options for later energy use. The supplied 75kWh figure describes supported battery-bank capacity, not an included battery or a guaranteed backup duration. Battery voltage, communication compatibility, current limits and parallel-bank requirements must be verified before installation.

Monitoring and Installation Protection

The colour touch LCD provides local monitoring and control. An optional external temperature sensor supports battery charging management when correctly installed. The IP65 enclosure offers dust and water-jet protection, not immersion protection; installation must follow the manufacturer's environmental and ventilation requirements.

Warranty

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

Frequently Asked Questions

What power capacity does this inverter offer?
The supplied specifications list 12kW output and up to 18kW PV input capacity. These are different ratings and should be considered separately when designing your system.

Does it support solar panels and battery backup?
Yes, it supports suitable solar arrays and compatible lead-acid or lithium-ion batteries within a 40–60V battery range. A correctly configured battery system and backup circuit can support selected loads during outages. Runtime depends on usable battery capacity and connected loads.

Is it suitable for commercial projects?
Its three-phase design can suit homes with three-phase supply, offices, shops, warehouses and other appropriately sized commercial installations. An installer must assess phase loading, motor starting currents and backup requirements.

How does dual MPPT help?
MPPT trackers adjust solar operating points to improve energy harvesting within their supported limits. They do not eliminate shading losses or guarantee generation under every weather condition.

Are batteries and the optional temperature sensor included?
Battery compatibility and an optional sensor are described features; neither is stated as included with this inverter.

Professional System Design

Confirm the exact model datasheet for PV limits, output and backup ratings, battery compatibility, dual-output behaviour, earthing and protection requirements. Grid-connected and net-metering installations require applicable utility and regulatory approvals. Do not assume seamless or uninterrupted power under every operating condition.
