EVBoiler - the easy solution for reducing energy consumption from the Grid
In an example of a solar installation, 6 panels (290Wp) will generate an average 1400Wp of energy (at 80% rate) that is used for water heating using the EVBoiler. With 1200 hours of full sunshine per year, the total energy production is 1680 kWh. This means there is no need to take 1.68MWh from the grid!
Take your chance and start saving money by reducing your demands for the energy from the Grid.

EVBoiler Storage Water Heater AC-DC GridFree Direct Solar
Smart way of producing hot water generated by the electicity from photovoltaic (solar) panels. Save the surplus solar energy for later use as a hot water. Perfect solution for electric water heating at any place.
EVBoiler - water heater storage solution with the direct power form the sun.
AC-DC power - works both with DC power and AC power! Get hot water from DC solar panels. Get hot water from AC in days with little sunshine. Pre-warm the water from DC panels during the day-time and keep the water warm at night from AC grid power.
3-way solution – works from DC, works from AC, has an internal heat exchanger to work from another heat source (e,g, gas heating)
GridFree technology – reduce the need for energy from the public grid by self generation of the part of the energy from DC solar panels
Direct Solar Energy - direct photovoltaic water heating – no thermal solar – direct DC power from solar panel. No need for a regulator or other electronics.
Flexible installation - allows to make flexible installation with 1 kWp, 1.5 kWp or 2kWp of solar panels.

Tracer Series - The best MPPT regulator for batteries
Tracer series controller adopts latest MPPT technology (Maximum Power Point Tracking) and advanced tracking algorithm to make the solar module operate at ideal voltage which the solar modules can product the maximum available power.
Compared to conventional PWM controller, MPPT technology increases the charge efficiency up to 30% and potentially decrease the power of solar array needed.
The ability to step-down the higher voltage solar module to recharge a lower voltage battery bank greatly increases system design flexibility. The cable size can be reduced because of the small current from the solar array.

Testing of solar panels
Some customer place “void claims” that their solar panels have “poor performance”. In all cases such claims were proved as invalid. The solar panels are professionally tested high quality products. The performance and specification parameters are verified several times before leaving the factory.
To honor the claims of our customers, we may perform additional tests to prove the performance of the solar panels. We use the comparative method. We compare two panels using calibrated (identical) ohmic loads. At the same location at the same sunshine level, the results of the power performance are compared.
The photo shows the test results. The so-called “defective panel” generates 6.26Amp while the nominal panel makes 6.23 Amp.
FAQ: What is the quality inspection for solar panels?
During production the solar panels are inspected several times and electrical parameters are tested repeatedly to make sure the panels are 100% quality.
The cells received from the cell factory come with an inspection report giving test results for each cell. In the module factory, the cells are once more inspected and sorted to several subcategories based on their nominal specifications from the manufacturer. The goal is to select groups of cells that match perfectly.
Each group of cells is once more tested by light exposition to verify that the specifications of the cells within the group are really identical.
After the cells are soldered together they make a section (also called a branch). Again, each section is inspected and tested electrically to make sure the parameters of the section are identical after the soldering is done.
The sections are placed together on the back sheet of the solar module. In this moment the whole module is inspected by infra-red camera to see any discrepancies or problems. The infra red camera will discover any kinds of possible quality problems.
The goal is to be 100% sure about the quality before the lamination of the solar module. The reason is simple: after the module is laminated to the front glass, there is no more way to repair or change anything on the module.
After the model is laminated, the alum frame is added and the junction box is installed. The final product is tested again on the illumination testing machine. The machine will report the total specification of the solar panel including the MPPT values.
Due to the strict inspection, it is possible to make sure that all panels are within the guaranteed parameters. It is mostly unlikely there would be a solar panel that would have a manufacturing defect that would escape the strict inspection.

Improving thermal codition of flexible panels
Placing flexible solar panels on “Makrolon Plaxiglas" type structure will improve the airflow behind the solar panel backsheet. This can help cooling the solar panel down and increase the performance in hot weather periods.

Solar Controller Monitor for TRACER series to read data using a PC
The Tracer series solar charge controllers with MPPT have a proprietary RJ45 connector with a digital output of the system values. The Solar Controller Monitor (code REG/COM/PC) allows to connect the Tracer series to a PC with Windows and to read the data from the Tracer controller.
The Solar Controller Monitor is supplied with a PC application to read the data. This application is provided as it is, free of charge. The PC application is READ-ONLY. It allows reading the data and logging the data to a file. The logged data can be later used to analyze the charging/discharging cycles.
