Inv On/Off Switch Operation
LED Indicators
The momentary push-button switch on the front panel controls the operating mode of the
inverter:
: When in Search mode, push the Inv On/Off switch once to turn the inverter to On
mode. The inverter will produce AC power from the batteries until the low battery cut-off
voltage is reached, or until the power switch is pressed once again.
When equipped with the optional battery charger, the device will remain in On mode until
approximately 20 seconds after AC power is applied, when it will stop inverting, pass
through the current, and begin charging.
: When in On mode, press the On/Off switch once to turn the inverter Off. The inverter
draws very little power when in Off mode.
The front panel features four LEDs which operate in the following manner:
Error : - Low battery error; indicates
battery voltage is below low battery cutoff (LBCO)..
- High battery error; indicates battery
voltage has exceeded 15.1 volts for about 25 seconds.
- Overload error; lights steadily when load
exceeds rated capacity.
Charger: - AC is present but inverter has not
transferred to charge mode.
- charger is charging in bulk/absorption
mode.
-charger is charging in float mode.
Power: - inverter is in Search mode.
- AC is present on output.
Flickering: inverter is charging.
- inverter is off.
Status: - battery voltage exceeds 12.8 (25.6 for 24-volt)
- 12.5 to 12.7 volts (25.0 to 25.5)
- 12.3 to 12.4 volts (24.6 to 24.9)
- 12.0 to 12.2 volts (24.0 to 24.5)
- 11.8 to 11.9 volts (23.6 to 23.9)
- less than 11.8 volts (23.6 volts for 24-volt system)
Before beginning the installation, disconnect any power supply that you will be connecting
to this device. This section describes mounting, installation, and cabling,
Mount this device on a shelf or table in a clean, dry, well-ventilated location close to the DC
supply. DO NOT locate this device in the same enclosure with batteries. Liquid lead-acid
batteries may produce explosive gases and must be well ventilated. Sealed batteries may
be located in the same enclosure. Allow adequate clearance around this device for proper
ventilation.
Search: Push the Inv On/Off switch once to enable Search mode. The power lamp will
flash slowly in this mode. When in Search mode, the inverter emits a pulse testing the
output circuits for loads. If a load greater than eight watts is present on the output circuit,
the inverter turns On and provides AC power to the circuit for as long as the load is present,
automatically switching back to Search mode when the load is no longer present.

Transfer Sensitivity (SB Option Only)
Use #6 AWG battery cables, Cables are available in 3, 5,
and 10 foot lengths (BC3, BC5, BC10). Strip the
insulation about ½“ (12 mm) from the end of each wire.
Using a Phillips screwdriver, remove the six screws from
the top and side of the inverter and remove the cover.
Loosen the uppermost strain relief by rotating the cap
counter-clockwise, and insert the stripped end of the
positive (+) battery cable through the strain relief and into
the cable lug marked ”Battery Plus” on the PCB. Using a straight-blade screwdriver,
tighten the screw in the lug to 12 foot-pounds, then tighten the strain relief. Repeat for the
Battery Minus (-) cable. Replace the cover and reinstall the cover screws.
On AC outlet equipped models, just plug-in the load or appliance to the pre-wired outlet on
the back panel of the inverter. On units equipped with a factory-installed battery charger,
wire the AC input circuit to the charger board as shown in the section of this
booklet (some configurations may include a pre-wired AC line cord).
The standard TS series inverter requires no user configuration. When you have the
standby battery charger option or the PV controller option, you can configure the TS Series
for your specific system requirements. Configuration options include battery discharge
voltage (LBCO), AC voltage transfer sensitivity, and battery type. To change configurations,
disconnect any AC or DC power supply and loads from the unit and remove the cover from
the chassis. Remove or install the jumpers from the configuration pins as shown in the
illustration at right. If the unit is equipped with the SB charger option or the PV option, it
may be necessary to remove the option board to gain access to the configuration jumpers.
See the illustration on Page 9 to locate the configuration pins on the main printed circuit
board (PCB)
You can set the inverter to stop inverting when the battery to which it is connected has been
discharged to 11.7 volts for 5 minutes (shallow discharge) or to 10.6 volts for one minute
(deep discharge). The factory setting is Deep discharge Shallow discharge means less
battery stress and more charge/ cycles. Deep discharge allows the batteries to be
discharged almost completely. This usually results in somewhat shorter battery life, but
fewer charge/discharge cycles. To select Shallow Discharge, remove the jumper from the
configuration pins. For Deep Discharge, the two pins must be connected by the jumper.
The TS inverter can be configured to begin inverting whenever grid voltage falls to 95 volts
RMS (UPS mode) or to delay transfer until line voltage falls to 80 volts RMS (Gen mode).
The factory default, UPS mode, is relatively intolerant of line voltage fluctuations to prevent
Options
User Configuration Options
A jumper is a small, rectangular piece of plastic with two square
holes in it that fit over two pins as shown in the illustration at left.
A jumper contains an internal conductor that joins the two pins,
completing a circuit. When the jumper is removed, the circuit is
interrupted. Jumpers are often used for changing configuration
parameters. When a jumper is not connecting two pins, it can be
stored by slipping it over just one of the pins instead of both. This
will have no effect upon the configuration, but will keep the
jumper handy for future use.

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.
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.
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 are designed for high cranking power, not deep cycling. Don't use them.
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.

Sealed Gel Cell
Monthly Maintenance
Sealed gel cell batteries do not use battery caps because the electrolyte is in the form of a
gel. This allows the batteries to be mounted in any position without spilling. Other
advantages are: no maintenance, long life (800 cycles claimed) , and low self-discharge.
The disadvantage is high initial cost and the possibility of damage from overcharging. Don't
confuse sealed batteries with maintenance-free batteries - the latter are typically standard
liquid electrolyte batteries with no caps for adding water; when the electrolyte gets low you
replace the battery. For best results, use the Battery Temperature Sensor (BTS) option with
sealed batteries.
Check the level of the electrolyte in each battery at least once a month. It must be above
the top of the plates, but not completely full. Most batteries have a split plastic cup under
the caps, which the electrolyte should just touch when full. Don't overfill the batteries, or
the electrolyte will spill out of the batteries when recharging. Refill batteries with distilled
water only - "spring" water and regular tap water may have high levels of minerals that can
poison the battery chemistry and reduce battery life.
Check the battery cable connectors for tightness and corrosion. To remove corrosion,
disconnect the cables and carefully rinse with a mild solution of baking soda and water. DO
NOT ALLOW THE SOLUTION TO ENTER THE BATTERY. Rinse the top of the battery
with clean water when finished. Remove stubborn corrosion with a wire brush. Any
automotive parts store will have a wire brush tool specifically designed for cleaning cable
lugs and battery terminals.
To prevent corrosion from forming on the battery terminals and cable lugs, coat them (only
after installing the cables) with liquid neoprene or anti-corrosion grease available from any
quality marine, automotive or battery equipment supplier. Do not apply any material
between the terminal and the cable lugs - the connection must be metal-to-metal. Apply
the protective coating only after the bolts are tight.
Batteries may be connected in series, in parallel, or both depending upon your purpose.
To increase voltage, connect two or more batteries in series as shown in the diagram
below. The voltage of the combined batteries will be the sum of the voltage of all the
batteries. The amp-hour capacity will remain unchanged. To increase amp-hour capacity,
connect two or more batteries in parallel as shown in diagram B. The amp-hour capacity of
the combined batteries will be the sum of each individual battery, but the voltage will remain
unchanged.

Options
Field-installed options for the TS Series include either a three-stage standby battery
charger (SB option), a battery temperature sensor (BTS option), and a remote control (RC8
option).
Standby Battery Charger
The Stand-By (SB) charger option features a three-stage automatic battery charger with AC
pass-through relay mounted on a PCB that can be field installed, includes an AC power
supply cord and circuit breaker, and enables transfer sensitivity, battery selection, and
depth of discharge.
Battery voltage is varied during the three stage battery charging process, as follows:
-During this initial stage of charging, the Charge LED flashes about once each
second and the inverter charges at a constant current. This causes the battery voltage to
rise over time. When battery voltage reaches the bulk voltage setting (see
for voltage settings), the charger begins the absorption stage of
charging.
-During this phase, the charge current gradually reduces while the battery
voltage is held constant for two hours at the bulk voltage During the ABSORPTION stage,
the Charge LED flashes rapidly.

FLOAT - During this stage the voltage of the battery is held at the FLOAT voltage setting.
Full current from the PV array can be provided to the loads connected to the battery during
the float stage. When the battery voltage has reached the FLOAT stage, the status LED
will be steady green.
When the battery voltage drops below the FLOAT setting for a cumulative period of one
hour, a new BULK cycle will be triggered. This typically occurs each night. If the battery
is full at the start of the day, it will receive an ABSORPTION charge for one hour and then
be held at the FLOAT setting for the remaining period of the day. Should the battery
voltage drop below the FLOAT setting for a cumulative period of one hour, another BULK
and ABSORPTION cycle will be initiated.
This three-stage charging process results in faster charging compared to on-off relay type
or constant voltage solid-state regulators. The final FLOAT voltage setting reduces battery
gassing, minimizes watering requirements and ensures the complete battery recharging.
Warning: Do not connect the AC power cord to
the AC out terminal. You may damage the unit.
Inverter to Charger Transition
On inverter models equipped with the three-stage internal standby battery charger, the
charger and an automatic transfer relay allows operation as either a battery charger or an
inverter, (but not both at the same time). An external source of AC power (e.g. shore
power, generator, and/or utility grid) must be supplied to the inverter AC input in order to
allow it to operate as a battery charger. As long as AC power is supplied to the charger, it
operates regardless of the position of the On/Of switch. When operation as a charger, the
inverter’s AC output is provided by the external source.
The inverter automatically becomes a battery charger after a 10-second delay whenever
AC power is supplied to it. This delay is built-in to provide time for a generator to spin-up to
a stable voltage and avoid relay chattering.

The inverter’s AC input connects internally to the inverter’s AC output while in the battery
charger mode. A 15-amp pass-through relay accomplishes this switching, protected by a
15-amp circuit breaker.
An optional battery temperature sensor (BTS) can be field-
installed at anytime. Remove the lid of the chassis as described
in the Optional Standby Battery Charger section. At the bottom
right-hand edge of the TS board are two RJ11 plug jacks. The
top-most jack is labeled ‘BTS.’ Remove one of the 7/8 -inch
knockout plugs in the chassis endplate and install the BTS
through this opening and plug it into this jack. Sandwich the
BTS sensor between any two of the batteries in your system.
The BTS will enable the SB charger to ‘fine tune’ the charging
voltage based on temperature and lengthen battery life
The optional RC8 remote control unit duplicates the Power On/Off Switch on the
inverter/charger and is coupled to the inverter. It connects directly to the six-conductor RJ15
phone jack labeled RC8 on the bottom right of the inverter PCB (see illustration on Page
9). Use the Trace remote cable provided with the RC8 because it is tin-plated stranded
cable with gold-plated connectors.
Cut a 1-7/8" diameter hole. At least 1½" of clearance is required behind the hole. Next drill
the two holes needed to screw the installation to the wall. After routing the Trace remote
cable, plug it into the six-conductor, RJ15 phone jack on the TS main PCB.
