grid-connected inverters Photovltaic On-grid power generation systems are composed of photovoltaic modules (array), photovoltaic On-grid inverter power supply, and metering device. Photovoltaic modules (array) convert solar energy into direct current energy, then through the On-grid inverter directly, the inverter part convert the direct current energy into the alternating current energy of the same frequency and phase, and feed in the grid. Batteries are not needed, so the On-grid system will become more effective with lower cost.ModelBF4000Power(W) 4000 Most power >or ≥the power’s 20% i/p voltage(V) 120/180v MPPT efficiency 98% Most i/p current(A) 10 o/p power(W) 4000Allow mails o/p(V) 110,220,230,240(±10%) Allow mails frequency(Hz) 50&60(±0.5) THD <3% Power factor 0.97 Mostly efficiency 94% Europe efficiency 92.4% size(mm) 450*497*205 Communication ports RS232 Night power expenditure <0.5W (AC) / 0 W (DC) Power factor >0.98 Island Effect Protection VAC; FAC UL 1741, IEEE929 Short circuit protection Current controlled Internal consumption during operation <7W (DC) Internal consumption during stand-by <0.5W(AC) Reverse Polarity Protection Diode DC voltage ripple VPP<% Defend grade IP20 /IP65 Operational environment temperature -10- +40 Operational environment humidity 15-95% electromagnetic compatibility EN50081,part1 EN50082,part1 Grid disturbance EN61000-3-2 Grid text DIN VDE 126 Protections Protection against short-circuit,reversePolarity protection,lone-island domino effect protection,protection against over-load,grounding protection
