SOLO-BUCKET Performance

SOLO-BUCKET is constantly undergoing testing to meet international certification requirements but more importantly to provide the ultimate end-user experience. Below you will find some common test data and information.

Test #1 Powering the Lights

SOLO-BUCKET is supplied standard with four high quality LED lamps on 5m cables. The lamps are rated at 5 Watts each. In order to establish the total running time of the lamps until the battery is depleted, we have run the four lamps on a SoloBucket™ Basic unit with a 30Ah battery - not connected to solar module. The controller is designed to allow 80% maximum depletion of the battery. This will prolong the battery life. The theoretical battery power available is 288 watt-hours (Wh). In standard operating conditions, the four lamps ran continuously for an average of 830 minutes (13.8 hours). This is a total of 276Wh and works out to within 5% of the battery safety margin.

Test #2 Charging the Battery

The 72 Watt flexible module is supplied with the SOLO-BUCKET SOlO1 model which can house between 8Ah Gel batteries and a 30Ah LiFePO4 battery. The charge time to take the 30Ah battery from 80% depletion (controller prevents the battery from being 100% depleted) to fully charged can vary depending on the location, orientation of the module and many other factors. In the Southern Hemisphere at -33º latitudes, without shading at peak irradiance season, the battery is charged to 100% in an average of 3 hours. The module is placed on the ground at horizontal position, uncleaned and charging begins at approximately 06h00. These tests are real-world, non laboratory in order to replicate actual performance. No load is used during the tests. Using the smaller capacity 8Ah or dual 8Ah variations will yield different results. An 8Ah battery will charge much faster, but delete much quicker due to the lower capacity.

Test #3 Charge and Use

A common question asked is whether the system can adequately charge during solar hours while providing power to devices. In our real-world tests we have shown this many times with a variety of loads. A single SOLO-BUCKET with 72 Watt module and 30Ah battery will adequately supply power and charge at the same time. The load limit is 10A and therefore any draw greater than this will cause the controller to enter safety mode. If the full 10A was drawn continuously, the battery may only last just over 2 hours without being connected to the solar module. Smaller loads such as laptops, chargers and LED lights will run all day while the battery is charging without any issue. Continuous supply such as fan based coolers (shown in picture) run effectively all day cooling by approximately 20˚C from ambient temperature. Since they are not controlled by thermostat they will deplete the battery once the module is out of solar hours.

Test #4 Double Up

The SOLO-BUCKET Hub modules can be stacked and connected to create larger off-grid solutions. It is more than possible to slowly grow an off-grid solar solution for your home, school, business by incrementally adding SOLO1 units. Harnessing the power of modular technology allows for systems to power much greater loads. Water pumps and other devices requiring power which are located in off-grid locations can benefit from simple deployment and setup of a large system.
