any protection of the inverter is triggered, the inverter will cut off the power supply and load immediately and enter the protection mode, and the alarm sound will be issued by the beeping device to remind you. The upgraded circuit chip is and more , and the stable voltage improves the conversion rate. Refined pure oxygen-free pure copper wire core has good conductivity, stable voltage and no heat, lower resistance and more power saving. A of smart chips, rapid response to security upgrades, and multiple intelligent protections that the inverter is fully during use. 't worry about power outages, household appliances can be used outdoors, and can support scenes. Notice: 1. It cannot be connected to the power socket of the household grid for use. 2. connecting the battery, distinguish the positive and negative poles of the battery. 3. Pay attention to waterproof, moisture-proof, drop-proof and pressure-proof.
