2.2 Battery Charger Of Stationery/Service Battery
The charger automatically starts when the appropriate qualified power is connected, either from grid, generator or solar.
With multiple charging stages (soft start-bulk absorption float-recycle), PM200 is designed to fully charge battery quickly. To guarantee
the optimal charging for batteries of different states, the PM200 features Microprocessor-controlled charging algorithm. The Float and
Recycle charging programs guarantees that the battery condition does not change despite being connected for a longer period.
Battery temperature compensation charging
The BTS PM30 (Battery Temperature Sensor) supplied with PM200, measures the temperature of the battery and automatically adjusts, in real
time, to charge the battery properly at compensation rate of – 4mv±10%/°C/cell. In case BTS is not present, the PM200 will use 25°C as default.
Voltage compensation charging
With a voltage sensor PM30 the PM200 can, if required, automatically adjust its output to compensate the voltage drop caused by a cable.
This assures the right voltage is being delivered for optimal charging.
Adjustable charging capacity
Users can adjust the charging current by specifying the battery capacity. The charging current is set at threshold rate of 10% the of the
battery capacity (I = 0.1C) by default.
Lithium battery charging
The PM200 can be configured to charge Lithium battery. With the Lithium battery, the max charging current will automatically be set at
30% of battery capacity (Imax=0.3C).
2.3 Vehicle Battery Charger
Along with a powerful charger for service battery, PM200 offers a float charge of up to 3A to keep the starter battery charged, whether
connected to the AC main or PV. When starter battery is less than 12.4V, the PM200 starts charging after 30 minutes delay and stops
charging when voltage reaches 12.8V.
2.4 Power Supply Mode
If no battery is attached to PM200 unit, it will work as a power supply automatically with a 12.8VDC output.

2.1 Multiple Inputs
PM200 master power unit may have many
sources at one time. These sources include the AC
mains, solar panel and starter battery (Auxiliary).
Only one of them will be dominated to provide
power at one time, even if all are available,
priorities are listed to the right.
