FAQs - Mobile MaxTM and MaxPowerTMFrequently Asked Questions

|||||
Q1. What is the primary difference between the Mobile MaxPure (MMP) and the Mobile Max (MM)? A1: The MMP
is rated at 3.4 kW whereas the MM is 1.7kW. The MM units are hard mounted
on a trailer; with the MMP the trailer is optional. The MMP can provide
water purification either by filtration and ultra violet light for
fresh water applications or reverse osmosis, and filtration for salt
water applications. The MM units pump water for displacement and irrigation
purposes, for instance. Q2. What is the primary difference between the standard Mobile Max (MM) and the Mobile MaxPower (MMPower)? A2: The standard
MM includes the trailer, solar array, pumping controller and 1HP pump.
The MMPower includes the MM standard features plus a 3 kW, 120 volt AC
inverter; 20 kWh battery bank; 12 volt power supply; AC/DC load center;
and charge controller. Q3. What are the pumping capabilities of the Mobile Max and Mobile MaxPower units? A3: The MM units can pump an average of 200 GPM or 12,000 GPH at pumping heads of 15 ft during daylight hours. The MMPower unit can pump over 100,000 GPD at pumping heads of 15 ft
including some evening hours drawing on the solar power stored daily
in the 20kWh battery bank. Q4: What are the key trailer specifications for the MM? A4: The trailer
is 18 feet long by 7 feet 2 inches wide. The trailer is rated at 7000
GVW. It has tandem axles with electric brakes on each axle. Full
technical specs are available if needed. Q5: What pre-deployment site preparation is required prior to operation? A5: The unit
should be placed on a solid, level surface. This may be directly on the
ground or on a concrete pad, depending on your site conditions. Ideally,
the deployment location is no more than 50’ from the water source and
the solar panel should be facing towards the sun. Wheels should be chocked
to prevent accidental trailer movement. Q6: What type of batteries are in the Mobile MaxPower? A6: There is
a 20 kWh battery bank consisting of sealed, gelled electrolyte, batteries.
Since they are sealed, they are “maintenance-free,” they cannot leak
battery acid, and no fumes are produced. They are certified as “non-spillable
and non-hazardous” and can be shipped by air without special packaging
containers. Q7: How long will the batteries last? A7: Battery life
is a function of several factors: How often the batteries are discharged
(less is better); the depth of the discharge (shallow is better than
deep discharges); the ambient temperature the batteries operate in; and
the number of years in service. The battery manufacturer provides a one
year warranty regardless of where the unit is located. We have batteries
that have operated in tropical environments for 5 to 7 years. Q8: What is the warranty for the Mobile Max and Mobile MaxPower and individual components? A8: The unit is warranted for ninety (90) days from shipment. Once the unit leaves the WorldWater loading dock, any damage that might be incurred during transportation is the responsibility of the purchaser. The unit is packed securely. Pass-through warranties for some of the components are: Batteries are
warranted for one year. OutBack charge controller, inverter/charger,
and system controller are warranted for two years. The solar panels have
a 25 year design life. Q9: Does the end user need to purchase anything else in order to make the units operational? A9: No. All necessary items are included, either installed on the unit or by WorldWater. In addition, the unit is tested at the factory as a total system with the batteries, pumps and electronics, completely assembled. The only onsite assembly is plugging the extension cord from the submersible pump into proper receptacle on the unit and attaching the hoses. Typically within 15 to 30 minutes after positioning the Mobile Max or
Mobile MaxPower near the water source, the unit can be operational. Q10: What maintenance is necessary for optimal operation of the Mobile Max and Mobile MaxPower? A10: Regular
cleaning of solar panels to remove dust and debris will allow batteries
to be optimally charged at all times. During high wind events the
trailer should be anchored or stowed in a protected area.. Q11: What safety features does the Mobile Max and Mobile MaxPower display? A11: The MM and MMPower provide
for electrically protected circuits to prevent accidental short or over
current draw from damaging the system. Q12: Are the Mobile Max and Mobile MaxPower waterproof and rugged enough to last in adverse conditions? A12: All electronics are marine
grade and sealed from the elements. The trailer is of heavy duty
construction and is able to be towed on non paved surfaces. Q13: Are there any environmental conditions that would prohibit operation of the units? A13: If high winds
are encountered (above 60 mph) the trailer should be anchored or stowed
in a protected location. The MM and the MMPower should not be used for
water operations in sub freezing temperatures. If the unit is to
be stored in below freezing environments the entire water system must
be drained and dried. Operation at latitudes higher than 40O will
result in less than optimum collection of solar irradiation. Q14: Will the glass on the solar panels break? A14: The solar array is rated for up to one inch hail stones. It is unlikely that a solar panel would suffer breakage during normal operating conditions. Glass breakage in solar panels used worldwide in mobile applications is extremely rare. If the glass does break the panels will still be producing solar electricity,
though at a reduced efficiency. If the broken glass presents any sort
of danger, the panel should be removed and properly disposed of. Q15: Does the Mobile Max and Mobile MaxPower perform on cloudy days? A15: Yes. Even on cloudy days there is a significant amount of solar energy collected by the solar array. Additionally, the on-board battery storage on the Mobile MaxPower provides for night-time water pumping and a power source. Q16: Does the solar array have to be constantly angled towards the sun? A16: No.
When the unit is first positioned, it should be placed so the solar array
is facing south when north of the equator, and facing north when south
of the equator. Once set, the array needs no further adjustment. Q17: Is it safe to run computers and sensitive electronic devices with the electricity from the Mobile MaxPower? A17: Yes.
The inverter system generates a pure sine wave which is ideal for powering
critical electronic devices. Q18: Is it safe to operate higher current devices such as power tools and floodlights from the Mobile MaxPower AC load center? A18: Yes.
The 3 kW inverter, coupled with the 20kWh battery capacity, can provide
power for tools. In addition, the inverter can handle twice the normal
operating current on inrush (there is increased current load when a power
tool is first started). |
