Page 8: Ac & Mppt Charger
www.sigineer.com When the inverter is turned on, the output voltage gradually ramps up from 0VAC to rated voltage in about 1.2 sec. This effectively reduces otherwise very high starting inrush current drawn by AC loads such as Switched Mode Power Supplies and inductive loads. This will result in lower motor inrush current, which means less impact on the loads and inverter. - Page 9 www.sigineer.com When the AC power charging process starts, the charging current will each peak in around 3 seconds, the charger may overload the AC input generator and drop its output frequency, making inverter switch to battery mode. It is suggested to gradually put charging load on the generator by switching the charging switch from minimum to maximum, and give the generator enough time to spin up.
