Installation Notes Installation should be carried out by a qualified professional to ensure safety and compliance with local regulations. Ensure the nominal battery voltage matches the inverter's input voltage (12V in this case). Use appropriately sized and shortest possible cables for battery connections to minimise voltage drop and ensure secure contact. The unit is designed for indoor use and should not be exposed to rain, snow, or liquids. Avoid placing the inverter directly above batteries, as corrosive gases can cause damage. Refer to the manufacturer's manual for detailed installation instructions and safety precautions. Before You Buy Verify that the 12V nominal battery voltage and 1kW continuous power output meet your specific system requirements. Consider your peak load demands; this unit offers 2000W peak power for starting inductive loads. If planning for ESS or grid-tie functionality, ensure you have or intend to acquire the compatible TBB E4 LCD Monitor and IC-METER. Assess your space requirements based on the unit's dimensions (462 x 255 x 144 mm) and ensure adequate ventilation. For parallel or three-phase configurations, plan for the necessary additional units and wiring. Consult with a qualified solar or electrical installer to confirm compatibility with your existing or planned system components. All specifications are subject to change by the manufacturer. Please verify details with the latest product documentation before purchase. This product is covered by a 5-year manufacturer warranty.
