SOLAR GRID TIE INVERTER 600W MPPT ADJUSTABLE BATTERY DURABLE DISCHARGE POWERITEM DESCRIPTION. Specification: Output voltage: 110V-220V / 220V-240V Output power: Battery mode 30W-400W Input voltage: PV 120-180V Bat 96V / PV 55-90V Bat 48V Input plug type: AU, US, EU, UKExternal dimensions: 245 163 55MM Work environment: -25 ° C80 ° C. PV grid-connected inverter operating mode 1. The grid-tied inverter has an automated working order, without needing to monitor. On detection the power output from solar panels, device will decide if the power was large enough to begin the conversion process. Conversation process includes 5 modes, Startup, Grid-tied begin, Standby, Stop, Fault-find. Startup – When the start button is on, solar panel and grid lines both connected in normal condition, inverter enters working condition. Grid-tied begin – Grid-tied begin mode is when inverter starts to convert the Direct Current fed through from PV solar panel to a stable Alternate Current and flow to the utility grid. To enable the maximum output of energy, the device uses MPPT control technology to track sun rays, this technology promises the maximum efficiency under different daylight and temperature conditions. Standby – Standby mode is when device detects insufficient power feeding through from the solar panel, or device detects abnormal status such as voltages, frequencies, and temperatures not in the permitted range, the device enters standby mode. Stop – Insufficient sunlight hence insufficient PV power feeding through to the device and device enters into the standby mode, when this condition continues and DC voltages falls below 12V for over 1 minute, the device will enter Stop mode. When error ocurs, fault find indicator starts flashing, device will enter Stop mode. Please see 3.4 error status on LED indicator.
