computer brownouts, and is preferred when operating devices that are sensitive to voltage
fluctuations. GEN mode is preferred when line voltage is provided by a generator, some of
which provide AC power with significant fluctuations in RMS voltage. To select UPS mode,
connect the two pins with the jumper provided. For Gen mode, remove the jumper from the
pins. Store the jumper by leaving it on one pin only. Transfer time from grid to inverter is
about 8 to 12 milliseconds.
Battery Type (SB Option Only)
The TS Series can charge either liquid lead-acid (flooded) batteries or sealed, gel or
absorbed glass batteries. The difference is in the charge voltages. The unit comes from
the factory pre-configured for sealed batteries. To change to flooded batteries, remove the
jumper from the pin pair labeled Sealed/Flooded.
Selecting the Best Battery
There are many types and sizes of batteries available, including starting, deep-cycle,
sealed gel, and absorbed glass mat. Which battery is best for your installation depends
upon your unique circumstances. In order to help you choose, a discussion of these types
of batteries is found in this section.
Starting Batteries
Starting batteries are designed for high cranking power, not deep cycling. Don't use them.
Deep Cycle Batteries
This type of battery is best suited for use with inverters because they tolerate a greater
depth-of-discharge before being recharged. The most common type is the non-sealed,
liquid-electrolyte battery, which have removable cell caps for monitoring the electrolyte
level. When a cell is low, add only distilled water. Check the electrolyte level at least
monthly. Top-up after recharging.
A popular and inexpensive deep-cycle battery is the six-volt golf cart battery rated at 220
amp-hours. These can be cycled repeatedly to 80% of their capacity without damage. The
TS512 is a 12-volt system, therefore you must connect at least two of these batteries in
series in order to produce 12 volts. The TS524 is a 24-volt system and required four of
these batteries.
Some systems use the L16 type of battery: six-volt batteries rated at 350 amp-hours
available from a number of manufacturers. At 17 inches in height and up to 130 pounds
each, they may be difficult to place in mobile or marine installations.
Type 8D batteries are available in either starting or deep-cycle construction. Most common
are the starting version used to start very large truck engines. Make sure you purchase the
deep-cycle version. These deep-cycle versions are 12-volts and are rated at 200 amp
hours or so. Type 4D batteries are very similar in construction, but about one-third smaller.
