AGM Batteries are not harmed by high amperage charge and discharge so long as the input voltage is carefully regulated. Calculating the DC watts to amps I (A) = P (W) / V (V), where the current in amps is computed by dividing the power in watts by the voltage in volts. In Northern America and Western Japan, this usually happens 60 times per second, or 60Hz / hertz. This means theres 10% resistance. If inverters were 100% efficient, all of the power flowing from the battery would be inverted for use by the load, and the inverter would consume no power at all. To do this, resistors, capacitors, transistors, and other circuit components are used by the majority of inverters. Power is power. This cookie is set by GDPR Cookie Consent plugin.
