abelstamatin THERE ARE ONLY 2 TYPE ACCORDING TO INPUT VOLTAGE : 1). 11-22V (10,8-30VDC, 11-32VDC) WITH MPPT VOLTAGE AT 18V FOR 12V SOLAR PANEL, AND 2).23-50V (20-45VDC, 22-60VDC) WITH MPPT VOLTAGE AT 33V FOR 24V SOLAR PANEL. 36V SOLAR PANEL WILL NOT WORK WITH THIS INVERTER BECAUSE THE MPPT VOLTAGE IS ABOUT 51V AND THE INVERTER CAN'T MANAGE THIS INPUT VOLTAGE AND WILL SHOUT DOWN. ANY VENDOR CLAIM ABOUT 4 INPUT VOLTAGE RANGE IS JUST CHEAP CHINESE SELLING PROPAGANDA.

Q: what is the peak wattage and continous wattage?
尋ねた chandruasp に 2019-10-03 09:11:27
abelstamatin THE GRID TIE INVERTERS DON'T HAVE PEAK WATTAGE OR SURGE CAPACITY BECAUSE THEY DON'T NEED IT. THE CONTINOUS POWER IS 1000W BUT HAVING THREE OF THEM FOR 5 YEARS IN A HOT CLIMATE LIKE GREECE, I RECOMMEND 850-900W MAXIMUM ON INPUT FOR A LONG LIFE WITHOUT ISSUES.

abelstamatin IF YOUR INVERTER IS 120V AC THE MAX AMPERAGE OUTGOING IS 1000W DIVIDED BY 120V = 8,33A IF YOUR INVERTER IS 230V AC THE MAX AMPERAGE OUTGOING IS 1000W DIVIDED BY 230V = 4.34A IF YOUR INVERTER IS 120V OR 230V AC AND 10.8-30V DC, THE WORKING INPUT VOLTAGE IS 18V AND THE MAX INCOMING AMPERAGE IS 1000W DIVIDED BY 18V = 55,5A. IF YOUR INVERTER IS 120V OR 230V AC AND 20-45V DC, THE WORKING INPUT VOLTAGE IS 33V AND THE MAX INCOMING AMPERAGE IS 1000W DIVIDED BY 33V = 30,30A. IMPORTANT NOTE: THIS TYPE OF INVERTER DOES NOT SUPPORT 72 CELL SOLAR PANEL(OR 36V PANEL) BECAUSE THE MAX INCOMING VOLTAGE IS LIMITED TO 50 VOLT BY THE INPUT CAPACITORS ALL RATED 50V!!!!!

abelstamatin YES IS POSSIBLE BUT NOT VERY SAFE BECAUSE IF ONE INVERTER IS DAMAGED BY ANY REASON( LIGHTENING , HIGH TEMP. OR MOSFET BLOWING) THIS WILL DESTROY AUTOMATICALLY THE SECOND INVERTER BY HIGH CURRENT (POWER) ON INPUT . I RECOMMEND TO SPLIT THE 4 PANELS IN 2 PCS. FOR INVERTER 1, AND 2 PCS. FOR INVERTER 2 AND CONNECT BOTH INVERTERS IN THE SAME PHASE( IF YOU HAVE THREE PHASE POWER LINE). IF YOUR POWER LINE IS SINGLE PHASE IT DOESN'T MATTER IN WHICH SOCKET YOU CONNECT THE HEAT PUMP AND THE INVERTERS : THE RESULT WILL BE THE SAME. I HAVE 8 PANELS 250W24V AND 3 INVERTERS 1000W20-45V (3P+1INV, 3P+1INV, 2P+INV AND ALL THREE INVERTERS ARE CONNECTED TO THE SAME SOCKET ON MY ROOF. THE SYSTEM IS WORKING NON STOP ABOUT 5 YEARS AND STILL SUPPLYING A LOT OF KWH PER YEAR.

尋ねた BG181041551 に 2020-08-24 02:33:38
abelstamatin YOU CAN PUT ANY DC SOURCE , VARIABLE OR NOT,(LIKE BATTERY , DC GENERATORS, SOLAR PANELS,etc...) THE UPPER LIMIT IS 50 VOLT NOT 60V BECAUSE THE INPUT CAPACITORS ARE RATED AT 50V. ANY HIGHER VOLTAGE THEN 50V WILL MAKE THE INVERTER TO SHOUT DOWN BY IC PROTECTION AND NOT WORKING .
