First, the sine wave inverter technology indicators Table I: 10KVA inverter technology DC input indicators Rated input voltage (Vdc) 220V Rated input current (A) 37.4A DC input voltage range Operating voltage: 180V-270V power voltage: 190V --265V anti-irrigation noise current ≤10% AC bypass inputs allow bypass voltage (Vac) 220 ± 25% Rated input current (A) 31.8A bypass conversion time (ms) ≤5ms AC output rated capacity (VA) 10000VA Rated output power (W) 7000W Rated output voltage and frequency 220Vac, 50HZ rated output current (A) 31.8A output voltage accuracy (V) 220 ± 1.5% output frequency accuracy (Hz) 50 ± 0.1% Waveform distortion (THD) ≤ 3% (linear load) Dynamic Response time 5% (load 0 ← → 100%) power factor (PF) 0.7 Overload 110%, 30 seconds Inverter efficiency ≥85% (80% resistive load) Bypass conversion time ( ms) ≤5ms working environment dielectric strength (input and output) 1500Vac, 1 分钟 Noise (1 meter) ≤40dB Ambient temperature -25 ℃ ~ + 50 ℃ Humidity 0 ~ 90%, non-condensing Altitude (m) ≤1000 Mechanical standard rack size 374 × 482 × 266 (depth × width × height) (mm) Weight (Kg) 26Kg input undervoltage protection, input over-voltage protection; output overload, output short circuit protection: 1) In order to protect the battery Only when the battery voltage is within the voltage range of the power inverter to boot. 2) boot into working condition, as long as the battery voltage is within the operating voltage range, the inverter can work properly. When the battery voltage falls below the lower limit will be switched voltage low voltage warning, continued to decline to the lower limit of the operating voltage of the inverter off. Second, the use of sine wave inverter l Installation! Installation of the inverter must have some theoretical knowledge and practical experience of electrical technicians. 1) open the box, check that you have available; 2) Select ventilation, clean installation environment; 3) Confirm DC output voltage and (or) DC battery voltage and the input voltage of the inverter power requirements consistent; 4) Confirm positive and negative polarity power supply, high potential is positive, the low potential is negative (for example: -48VDC Power 0V terminal is positive, -48V side is negative, + 24V power supply + 24V for the positive side, 0V side is negative); 5) On the positive terminal of the inverter power supply positive terminal (marked "+"), the negative electrode connected to the negative terminal (marked "-"). Ensure reliable connection; before 6) DC input, to be self fuse (200A) as fault protection inside the machine without a fuse device! 7) on the AC input line access to the backplane after the "AC input" terminals: N- zero line, L- FireWire, E- ground. (Note: AC input line ground wire must be grounded AC input and AC output prohibit common zero line!!); 8) of the AC output line access to the backplane, "AC output" terminals on the rear of the chassis: N- zero line, L- FireWire, E- ground. l Power (recommended: first start inverter, then open the load!) 1) Check the DC input power and AC output is connected correctly and reliably; 2) if DC input switch, turn on the switch (the rear of the chassis) 3) Press "switch" button ("1" indicates open, "0" indicates OFF) Inverter "beep" sound, and self-test and show that has been opened. Description: self-test status - Inverter before stabilizing output, check the external environment and the inverter itself is normal, if the inverter and mains status parameters of all normal inverter steady work in the city or inverse Variable state (electricity main supply stable electricity output, battery main supply stability in the inverter output), this process takes about 10 seconds, during which the LED is lit from left to right, the cycle twice.
