When choosing a MAB Watermaker, it is good to consider which model best meets your needs –
both in terms of energy use and water production.
Please ask yourself these questions:
How much drinking water do I need per day?
How quickly do I want to produce it?
Will the system be powered primarily by solar panels?
Factors to consider
Battery bank
Lead-acid batteries → choose a pump with low power consumption.
Lithium batteries → provide greater freedom. The batteries can be recharged via solar panels or a generator.
Water requirement
A greater need may justify a more powerful pump that produces more water in a shorter time.
Price
The budget is crucial.
More powerful systems cost more, but also provide more water per watt.
Location and space
Do you have space for a system with one or two high-pressure housings?
Or would a more compact model like a shorter high-pressure housing 2521 be better suited?
12 volts DC
Slightly more energy efficient (see table).
However, it requires careful wiring and can be expensive at high currents, such as 80 A.
230 volts AC
Reduces the need for bulky cables and expensive installations.
Often the easiest and most economical option for longer cable runs.
Energy comparison
To make the choice easier, we have produced a table that shows energy consumption (Watts) in relation to the amount of drinking water produced (liters). The table also includes consumption from the boost pump, fan and any inverter (12VDC–230VAC).
The tests were done with a Sunwind 1500W sine wave inverter.
Important things to consider when using a powerful 12 VDC motor (1 hp)
When using a powerful 12 VDC 1 hp motor, it is crucial that the battery cables are sized correctly to handle the high amperage.
Additionally, all contact points must be secure and provide a good connection to avoid problems.
If this is not met, the high currents can cause the contact connections to overheat and, in the worst case, burn out. This can result in a short circuit, which can not only damage the electrical system but also pose a serious risk to the motor. In the event of extreme overheating, the contact connections can come loose or crack from the heat, which in turn can cause an internal short circuit in the motor. This can lead to extensive damage or total destruction of the motor.
To avoid these problems, it is important to:
✅ Use cables with sufficient dimensions to handle the current.
✅ Ensure that all contact points are properly connected and in good condition.
✅ Check and maintain the connections regularly to detect any signs of overheating or damage in time.
By following these guidelines, you can ensure safe and reliable operation of your 12 VDC motor.
