Progress Solar TM Mobile Solar Light Towers Specification for SLT800 / SLT1200 Series

SOLAR GENERATOR

• Solar Systems
- Two (2) totally independent off-grid solar systems housed on a single customized towable trailer; each off-grid system is complete with a monocrystalline solar array, MPPT charge controller, LED floodlights, an automated light timer with manual on/off function and is connected to a deep cycle bank of batteries with a state-of-charge monitoring meter.

• Power Generation –800W and 1200W of solar power (optional wind power available)
- Monocrystalline solar arrays (5” cells, highest power / sq ft available)
- Automated steel actuators to raise and lower solar wings.
- (Optional) TeleStruts – telescoping, locking arms for additional support for the solar wings in high wind regions.
- (Optional) Wind Generator – adds power (at wind speeds >7mph) during the night hours and/or times when solar irradiation is not readily available (i.e. during inclement weather, cloudy days, etc).

• Automated Light Timer / Charge Control Module
- Light Timer(s) to enable automated, timed interval or manual lighting start/stop times (works independent from solar panels)
- Maximum Power Point Tracking (MPPT) charge controller(s) to maximize solar power gained and to prevent over or under charging of batteries. Performance data from the charge controllers can be downloaded.
- Temperature controlled cooling fans provided where needed.
- Hour meter(s).

• Power Storage
- 24 Volt DC deep-cycle, battery bank(s) comprised of flooded or AGM (sealed, no maintenance) batteries; 840 – 900Ah combined capacity of battery banks.
- AC dual battery bank charger – 40Ah dual battery bank rapid-charger for backup using generator or any other standard 110V/20amp, 50/60Hz (available 240V upon request) commercial electrical source. Lights can be operated while batteries are being charged.
- Battery State-Of-Charge Meter - Visual display in increments of available battery capacity.
- (Optional) 50 ft. 20amp electrical cord to use with battery charger.

• Trailer & Housing
- Durable, steel vented housing customized to store, protect and maximize functionality of power generation, power storage and light tower components
- Wheelbase 55” (same for all SLT models)
- Towing weight – 2,980 to 3,495lbs (varies based on model, options & battery package)
- Dimensions - 4.42 meters (174 inches) long x 1.37 meters (54 inches) wide x 2.13 meters (84 inches) high (same for all SLT models)
- Towing specifications & requirements – 2” ball size, tongue weight - est. 128 lbs.
- Forklift pockets on mast for high point access and on trailer base for low point access. Crane hook pocket on mast for high point access.
- Straight tongue – standard 2” coupler connection
- 4 per unit “D” rings used to secure unit during transportation
- (Optional) Lunette Ring (for Pintle hook) or BullDog connectors
- (Optional) Front outriggers with jacks (included in high wind package)
- (Optional) Chock/Lock to secure wheels
- (Optional) Dual Wheel Jack Stand.

Light Tower

• 3-stage light tower that can expand from ~12’ to 30’
• 4 per unit LED Flood Lights (~36,400 initial LED lumens) estimated life up to ~5-10x longer than standard metal halide bulbs; LEDs expected 50,000+hrs, L79

Note: LED pupil lumens (scotopic) appear brighter than (photopic) foot candle measurements indicated when compared directly to high intensity discharge lighting (like metal halide or high pressure sodium).

SLT800 Series

• Progress Solar Light Tower Standard Features including the following:
• The SLT800 uses two solar arrays of 400 watts each (combined 800 watts) instead of the 300 watt solar arrays (combined 600 watts) of the SLT600 series.
• The primary benefits are that the solar gain charging rate of the batteries is ~ 35% faster than with the SLT600 series.
• Approximately 35 to 42 hours of operation without any additional solar or AC recharging.
• Recommended for moderate to heavy users (light hours used), typically 5 day work weeks up to dusk-to-dawn; or longer for high solar irradiation regions.
• This is the most commonly used model for general equipment rental fleets.

SLT800-HVR-S - Equipped with deep-cycle batteries. Periodic maintenance is required to maintain proper water levels in the cells.
SLT800-HVR-N - Uses AGM sealed deep-cycle batteries. No battery maintenance required and AGM batteries are more resistant to freezing than flooded batteries.
SLTW800-HVR-N - Uses AGM sealed deep-cycle batteries. No battery maintenance required and AGM batteries are more resistant to freezing than flooded batteries. Includes the Optional Wind Power Generator.

SLT1200 Series

• Progress Solar Light Tower Standard Features including the following:
• The SLT1200 uses two (2) solar arrays of 600 watts (combined 1200 watts) each instead of the 400 watt solar arrays (combined 800 watts) of the SLT800 series
• Two (2) higher capacity MPPT controller(s) that can handle the increased voltage and current.
• The primary benefits are that the solar gain charging the batteries is ~ 50%+ faster rate than with the SLT800 series and ~100%+ faster rate than with the SLT600 which allows for longer run times year round and during sun challenged times or regions.
• Approximately 35 to 42 hours of operation without any additional solar or AC recharging.
• Recommended for the heaviest users desiring up to 6 - 7 days per week, dusk-to-dawn, year round applications.
• Note: The high wind package option is a standard feature for the SLT1200 series and is included in the price.

SLT1200-HVR-S - Equipped with deep-cycle batteries. Periodic maintenance is required to maintain proper water levels in the cells.
SLT1200-HVR-N - Uses AGM sealed deep-cycle batteries. No battery maintenance required and AGM batteries are more resistant to freezing than flooded batteries.
SLTW1200-HVR-N - Uses AGM sealed deep-cycle batteries. No battery maintenance required and AGM batteries are more resistant to freezing than flooded batteries. Includes the Optional Wind Power Generator.
