ANSWERS TO YOUR FREQUENTLY ASKED QUESTIONS

Question: How do BluOasis units produce water from air?

Answer: BluOasis units generate water via an atmospheric water generator which uses a standard refrigeration cycle to capture the humidity in the air.  The atmospheric water generator condenses the humidity into water and then the BluOasis unit treats it with ultraviolet light before allowing it to drain from the unit via gravity into a customer provided storage container.

 

Question: How much water will the system produce each day?

​Answer: The atmospheric water generator yield is a function of temperature and humidity. It works best in warm humid locations, with production falling off in cooler and dryer environments.  The BluOasis units will produce approximately 10 gallons (44 liters) of water over a 24 hour period from 80 deg F (27 deg C) air at 60% relative humidity. Note that the atmospheric water generator consumes 12kW over the course of the day so it needs to be coupled with a sufficiently sized array (around 3,000W) or tied to a grid/generator power source to achieve its maximum yield. The system can generate smaller amounts of daily water with smaller arrays. Through the remote monitoring application, you can set water or power priority mode so that the system optimizes generation by mode.

Question: Are BluOasis units cost effective?

​Answer: Yes. Most solar power systems require unique designs and parts from multiple vendors. BluOasis units were designed to be highly integrated and automated, making them easy to set up and simple to operate and eliminating the need for electricians to design and implement custom solutions. As a result, from a total installation cost basis, BluOasis and BluPower units are the most affordable turnkey off-grid power and water systems available.​ Further,  BluOasis uses an intelligent power switching panel to provide system reliability and autonomy, features currently not available on the market at this price level. 

Question: What equipment and appliances can I run with the BluOasis unit?

Answer: The BluOasis and BluPower units have two outlets that supply either Utility Power 220/240VAC up to 50 amps or Accessory Power at 110/120VAC or 220/240VAC up to 30 amps. This is sufficient to run most homes, cabins or remote job sites, including household appliances, power tools and washers and dryers.  The Utility Power Interface and Accessory Power Interface use the connectors shown below, which is dependent on inverter power output. The Utility Power Interface will be connected to a homes backup generator plug, or to the main breaker panel.  The Accessory Power Interface was designed to connect to a jobsite spider box for powering an array of tools or high load devices. Both interfaces can be controlled via the Power Interface Panel or by using the IoT enabled device website portal.

While operating high load systems it is important to monitor energy draw and battery capacity, as excessive use could rapidly drain the battery system.

Question: Can I run my entire home off of a BluOasis unit?  How do I wire my home to do that?

Answer: Yes, each BluOasis or BluPower unit is capable of running your entire home with 6kW or 12kW of output power.  The BluOasis or BluPower unit will be connected to your home the same as you would connect a backup generator.  The home, or facility, gets wired just like a standard grid-connected building.  The electric panel has an automatic or manual transfer switch that allows you to power the home from the grid or from your BluOasis / BluPower unit with single phase 110/220VAC or 120/240VAC.  You can augment the BluOasis / BluPower unit by connecting a backup generator that continues to power your home in "off-grid" mode even when the battery capacity is depleted.

Question: What type of generator can I connect to a BluOasis unit?

Answer: BluOasis and BluPower units can be powered / charged via an external generator to charge the internal battery and/or power external loads.  Generators are connected to each units via a standard L15-30 generator cord and plug and accepts 240 V AC power (not 120 V AC power).  Each unit has an auto-generator start connection to command the generator on in low battery voltage situations.

Question: Can I install additional solar panels later?

Answer: Yes, the BluOasis unit can handle up to six strings of arrays with a maximum of 4500W or eight strings with a maximum of 6000W depending on the model.  All strings must be matched to have the same input voltage, with a minimum of 60VDC and a maximum of 90VDC. We recommend you purchase your array kit from BluOasis to ensure system compatibility.

​​

Question: How long does it take to recharge the battery bank?

The system charge rate is a function of the solar array area. To determine the recharge time, divide the utilized battery capacity (in kWhr) by the daily solar harvest (in kWhr/day).  For instance, our BluOasis 1506 has a 15kWhr battery. If we assume it begins the day with 20% of its capacity, meaning 3kWhrs, it would require 12kWhr of sun harvest to fully charge.  This would take approximately 4-6 hours with a 3kW array.

Question: How does the weather impact my power generation?

 

Answer: The solar panels produce peak power on clear days and good sun angles (direct sunlight on the panels). Clouds will reduce power generation but still provide some power. The BluOasis and BluPower web interfaces provide local forecasts at your unit's location so that you can optimize your power use and/or water generation.

Question: What's the difference between lead-based and lithium-based batteries?

Answer: Lead-based batteries degrade as a function of the depth of discharge, while the lithium iron phosphate (LiFePO4) units will not.  In addition, lithium-ion batteries have a higher energy density, meaning more battery capacity per unit volume.  Lead batteries support 2000 cycles at 50% depth of discharge (DOD) and 1000 cycles at 80% DOD.  Lithium batteries support 3000 cycles at 100% DOD.  For these reasons, our high performance and high cycle units use lithium iron phosphate batteries.  Lead batteries provide a cost-effective solution for vacation cabins where there are not a lot of cycles.

Question: Why do you use lithium-iron batteries versus lithium-ion batteries?

Answer: Lithium-Ion batteries are unstable when overcharged and can catch fire if the battery management system fails. Lithium Iron (LiFePO4) batteries, while slightly heavier, are more stable chemistry and do not have this failure mode. 

Question: What maintenance does the system require?

Answer: The BluOasis water generator has a filter that should be changed once or twice a year depending on the unit's operating location. Dust will impair air ingestion and thus water making performance. Dustier climates should change the filter more frequently. The unit comes with two spare filters.  The power system and batteries do not require maintenance.

Question: How do you ship each unit?

Answer: Each BluOasis unit is packaged within a crate individually, or with the full complement of solar panels and cables to create a complete solar power and water system. The crate is designed for ease of unit offload using a folding ramp configuration.

Question: Do you ship internationally?

Answer: Yes, we ship across the United States and internationally. Please contact us to inquire about shipping systems to your location.
