Introduction :
1. Description
  Pure sine wave Inverter/Charger design ensuring compatibility
  The Solar SP series is designed to have access to dual input source;
  one is AC source from a grid, and the other is DC source from a solar array.
  This series is a powerful all-in-one solution, not only delivering unsurpassed
  clean true sine wave output power and combining this with a selectable
  multistage battery charging current but also converting sunlight into clean energy.
  This series features durable and continuous 24-hour operation. Consequently,
  it is applicable to any kind of loads such as air conditioner, home appliances,
  consumer electronic and office equipment.
  The built-in 5-stage intelligent charger automatically charges any type of batteries
  without the risk of overcharge. The compact and modular design makes
  utility interactive installations easier and more cost effective. It is a high quality
  product that offers the best price-performance ratio in the industry.
2. Operation Modes
2-1 System Block Diagram
2-2 Normal Operation
  There are two main loops when AC utility is normal and DC electricity is generated
  from solar array under sufficient sunlight: the AC loop and the battery charging
  loop. The AC output power comes from AC utility input and passes through the
  static switch to support power to load. The battery charging voltage comes from AC
  utility input and is converted by AC/DC charger to support battery-charging power.
2-3 AC Utility Failure at Daytime (Solar Mode)
  The AC output comes from DC input from solar array through DC/AC inverter when
  the AC utility fails at daytime.

2-4 AC Utility Failure at Night (Battery Mode)
  The AC output comes from battery, passing through DC/AC inverter and static switch
  within during the battery backup time.
