1.1 Introduction to the Inverter

The TSW series inverter is not only an inverter but also contains a powerful intelligent charger.
Actually, it contains three modules in a single unit: inverter, charger and switch.
The TSW series inverter is a heavy-duty, continuous working module generating a sinusoidal wave
from a 24V, or 48V battery bank, which can supply energy to various loads such as resistive load
(heater), inductive load (air conditioners, refrigerator), motors (vacuum cleaners), and rectifier load
(computer). All TSW series are designed to work in heavy load condition. De-rating is not necessary.
It provides a rapid and complete charging process.
The TSW series are True Sine wave Inverters, not to be confused with Modified Sine wave models on
the market. Unlike the modified sine wave counterpart, a true sine wave inverter provides a pure
signal which will not interfere with some of the sensitive electronic equipment currently on the market.
The TSW series inverters provide a 120/240 Volt AC Split-Phase input and output. No external
transformers are required for step up, step down or balancing, thus saving added costs, installation
time, and several points of efficiency. The output provides 240 volts for well pumps, appliances, or
shop tools while providing 120 volts for standard circuits. Either side of the output line can supply up
to 75% of the total load. The input can accept the line or 240 volt AC generators. The transfer relay
is internal.
The smart charger can be set with different charging profiles and battery capacities to match in
various battery types and sizes. The switch module automatically diverts the energy transfer path
between inverter and utility source. When the utility source is lower than the transfer level, the path
switches to the inverter. Otherwise the load is conducted to the utility source. The transfer time is
1/4~1/2 of the total cycle time. The high power charger (100A) can charge a 24V/1000 AH battery
bank in 10 hours. For example, a single unit of Inverter TSW 3224 with a 1000 AH battery bank can
supply a 3200W workload for over 6 hours after a charge of 10 hours.
TSW series is an extremely good choice for utility back up power. However, it also can be used as a
UPS for computers.
