Heat your water with the sun to get a few more weeks of growing time in outdoor Tilapia ponds. This means your fish will grow more before they are harvested. We also used it to bathe the dog, heat the pool and an outdoor shower (if you wanted one). If you need more heat you can daisy chain two panels with water coming from the first panel outlet feeding info the second panel inlet. Insulation would make it more efficient if you choose to do so. Use your own discrepancy and read warnings of using Pex pipe. The one shown in the video is rated for over 150 degrees depending on the PSI. I hope you enjoy the video and it works as good for you as it has for us here at Grow Dinner Aquaponics.

600W Grid-Tie Inverter (0.6KW) Wide input voltage 22-60VDC SY-GWV-600W-220V
Smart grid tie inverter is a compact unit, which directly converts direct current into alternating current for powering appliances and/or office equipments and connecting to utility grid. The AC output from Smart Microinverter is synchronized and in-phase with the utility grid. It is a key device of power generation systems such as PV power generation system, wind turbine power generation system. Smart Microinverter specially optimized design to work with modularization of DC power supplies which includes the mainstream solar modules, 18V (36 cells), 24V (60 cells) and 36V (72 cells) monocrystal and/or Polycrystalline solar panels, wind turbines and batteries. Smart Microinverters are stabilization, reliable and high conversion efficiency items. It is the best choice for PV power generation systems.
Advantages of Smart Microinverter
1. Unique circuit design, choice of import industrial electronic components, higher efficiency, more stable performance.
2. Creative MPPT technology, efficiency more than 99%, faster reaction, more sensitive of reaction and more reliable of Maximum power point locking.
3. Parallel modular design, small volume, distributed installation, easy for system configuration, flexible for combination, strong expansibility of system.
4. Adopting high-frequency isolation transformer type, high efficiency, and high security.
5. Perfect electrical protection function.
6. Aluminum alloy housing, not rust, heat-resisting and cold-resistant as well as anti-corrosion.
7. Getting electronic circuit design, appearance design and other core technology patents.
8. Wide input voltage (22-60VDC), suit for different DC power supply.
