PHORAM DOWNLOAD HERE (In "files" Sector)
 
PHORAM Discussion here
First of all, I apologize for my English.
I'm almost certain that it should work with some other models of Hybrid inverters but unfortunately I have no way to test them.
The System Run Ok in Windows XP, Windows 7, Windows 8.0, 8.1 y 10.
Finally, what is promised is debt.
I share with all of you the First Version of PHORAM completely free of charge.
Due to lack of time and unforeseen inconveniences, the publication was delayed more than planned, unfortunately I have not yet reached the end of the initial implementation of the relays board functions, for fear of possible errors due to lack of field tests.
I have placed special emphasis on the visual aspect, on Monitoring and on quite complex and complete aspects that up to now at least I have not seen in any other tool that covers them all.
Both the beginner users of the friendly interface, but especially the more advanced ones will find very interesting things.
In short, this is the starting point of a project that will grow together with you. I do not live from this. I am a geologist, but with a large number of hobbies and I intend to continue with this development, as long as I have life and strength since solar energy has become my favorite. I have big plans for this project.
Next some of the screens.

I hope you like it !

Ampliation:  07.26.2018

I will try to expand the information on the Operation and current characteristics of the System.
From the Main Menu, Configuration, PARAMETERS, The First Tab corresponds to:
1. TAB General
[Pictures of your home]
In the Directory PHORAM \ Images you can save the photos of your home, business, etc. that will be changing dynamically in the Main Screen according to the Instant Load Consumption that the Power Inverter is registering.
The idea is that each one is different, for example with a small brightness in the place that you think working lightly on an original photo with an editor such as Photoshop or Gimp.
While you can upload images in .jpg or .bmp formats, the extension .png with a transparent layer is more aesthetic. This is left to your liking and imagination.
- Current Inverter and Bank of Batteries are Images defined by the User and must be placed in the Directory PHORAM \ Images
[Main Energy Source]
Here is defined if you have an Emergency Generator or NO or simply is not linked to the Home to any GRID.
You can define the Picture corresponding to your Back Up Generator
This is very important since from the Main Screen, in case of a power cut you can inform PHORAM that it changes the Main Energy from GRID to GENERATOR. This has an impact on several calculations and a way to show the Power and Accumulation from kWh to VA. We will discuss this topic in due time and according to the interest of some member.
-SUNRISE AND SUNSET
If you have decided to use the Weather Widget as it will be explained, the astronomical information of the sunrise time and sunset time of your location is stored in these fields.
In the event that you later decide to use the Relay Board features and the options of this system to automatically manage Solar Panel Chains with East / West Orientation to obtain the Optimal Power automatically, this information is important...

3. TAB: Coefficients and Factors

[Factors for calculating the Efficiency of the Solar Instalation]
The data corresponding to this Sector have as objective:
1) Establish with relative accuracy for a given day, month or year what should be the optimal or Nominal Solar Production according to the data provided by the Manufacturer of its Solar Panels and be able to establish comparisons with the Real Solar Production of that same day.
2) After at least one year of data collection, determine the normal curve of decreasing performance due to the aging of the Solar Panels.
3) It must be taken into account that the calculations obtained in this case do not contemplate the Losses of Conversion from Continuous Current to Alternating Current that will be characteristic of the efficiency of the Power Inverter and whose values are considered separately and shown in the Main Screen.
Note: The values of the Horizontal Solar Irradiation for a certain Latitude and Longitude you must obtain them, being able to consult for it the Web Site of the NASA, whose Link is added in this same sector.
[Values in local currency of kWh when Applicable]
In case you decide that this system runs in a unified installation to the electricity Grid, you can place here the value charged by the electricity company of the domestic GRID for the kWh.
In this way, you can know exactly the progression of the accumulated Amount to pay up to the month of your Energy Bill.
As this system is designed to also have control of the energy exported (GRID TIED) and it is possible that the kWh values for the energy it exports are different from the ones it imports, the fields are different. As my system is currently in homologation by the Local Regulations, I still can not export energy, so when this happens I will adjust the calculations and modify the PHORAM GRIDMETER to contemplate the Injection to the GRID.
[Coefficient of CO2 emission per kWh]
The electric power consumed by your company Local electricity, usually in any country, has different origins. For example, there may be an energy share generated by the burning of fossil fuels, nuclear energy, hydroelectric power, etc. This constitutes the energy matrix of a country or locality and its constitution generally varies from year to year. If you want to know how much you are contributing to make our planet atmosphere healthier, you should find out what is the pollution coefficient in Kg of Co2 per kWh.
[Empirical Coefficient Correction of Grid Energy]
This system has a GRID Energy Meter with daily, monthly, annual and PARTIAL RESET values indicated by the User.
The Energy Consumption of the Grid is measured based on sampling averages based on the information returned by the QPIGS command sent to the power inverter. Samples are stored every 10 seconds into the data base.
In order to calibrate what is measured by your particular power inverter with reference to what is measured by the Network Power Domiciliary Meter installed by your electric company, a value greater than one or less than one may be placed by trial and error. After a while, you can count on an error of less than 2% between what PHORAM informs you of your home consumption and what is actually measured and billed by your energy company.
When the Value is greater than or less than 1, the indication of the instantaneous WATTS corresponding to the LOADS or to the Consumed Energy of the GRID that appears on the Main Screen are indicated with [C]         GRID NOW= XXXX WATTS [C]    /   LOADS= XXXX WATTS[C]
--------------------------------------------------------------------------------------------
Ampliation:  07.28.2018


 
Note: First, I must indicate that a fault in the hardware (DC board of my power inverter) burns a transistor,  which is under warranty, after many comings and goings with MPP Solar and I have the dish they sent me and still  not I have made time to change it. this was in February that's why I had to suspend the calculation of the precise  SOC Objet of this TAB in a similar way to the BMV 702
5. TABS: BATTERIES
The image that appears here are your batteries according to the photo chosen in TAB 1.GENERAL
The objective of locating the values here is that the PHORAM can provide a much more accurate estimate of the SOC than the joke that appears as  a return of the capacity to the QPIGS command that is the same as that shown on the LCD of the Power Inverter. The equations on which the SOC can be established require these values with the highest precision,  all given by the manufacturer.
but "one of the key" is the measurement of voltage.  The most accurate is the value entered in the equations, the final SOC estimated according to the method used  by the Peukert exponent, the discharge rate that the manufacturer reports nominally the capacity (c20, c50 ...) and the Nominal Capacity,
Unfortunately, the precision of the measurement of the Voltage by the circuits included in these Chinese Power Inverters leaves a lot to be desired. They restinge the precision at XX.x Volts and the optimum would be precision at hundredth of volt, like the BMV702.
However, at least according to what I could investigate with my FLUKE Voltmeter is that the deviation in more (in my case) is constant although I recognize that it may not be constant due to a series of electrical interferences produced by both alternating current harmonics and values altered due to power differences received by instantaneous variable solar production (I detected this when trying to find the optimum correction coefficient to match the consumption indicated in my Home Energy Meter and my PHORAM Meter).
[Voltage Correccion Measured by Inverter (+/- X.xx) where 0.00 is for not correccion]
In short, if you make an average of three readings from your bank of batteries with a voltmeter or instrument of precision in 3 different load states, you can put here the deviation with its sign (+/-) 0.xx.
For the meticulous: I know that we are working with a significant number of more but also the adjustment of the Voltage will be valid to show more accurately what reported by the Power Inverter.
As in the case of Power measurements, when the Voltage Value of the batteries is shown in the Main Screen, it will appear with the symbol [C] in case this value is different from 0.
In a future version, as I intend to read the port of the BMV702, both estimates of the SOC will be found on the Main Screen.

7. TAB: Communications and Climate
[Weather]
With the aim put in the two fundamental aspects of design of this project, this is: to create a nice, attractive and simple interface but at the same time transform it into a tool of analysis of every possible professional aspect with the sufficient quantity of data collected, if You want to use the Weather Phoram Widget on the Main Screen.
I use the Service of www.openweathermap.org (at least for now since at least in my Region it does not have as much accuracy as others that I have been analyzing).
To be able to use it, you should obtain your username and password. When you register on the Site, you can obtain your Own API Key so that your facility can access the Climate information.
The fields of City and Country Code must obviously coincide with your locality, although here for the purpose of testing you could place those of any city / country in the world.
VERY VERY important is the displacement of the time according to your location. This you you must enter it manually. As a help from Phoram you can access the map of the Usual Uses of Wikipedia. According to the same you will daily astronomically know the Sunrise and Sunset Time, which as previously indicated, has an impact not only on the aesthetic aspect that determines the exact moment in which the Main Screen Changes from Day to Night / Night Day but especially in the next version for the operation of the RELAY BOARD and the corresponding Power RELAY for the automatic handling of Chains with East and West Orientation.
If you decide to use the Weather Widget, in addition, the Dynamic Wallpapers of the Main Screen will be activated with all sky images with different Cloudiness in a dynamic way and the Hourly Data of the Cloud and Temperature Percentages will be collected. real and specific of its location. Information that in the future, with more than one year accumulated in the Databases, I intend to use to improve the performance statistics of the solar installation and how the temperature, for example, specifically influences the panels and the production of Energy of your installation.
[Mail Settings and Mails Send]
In case you want the System to automatically communicate, through Mails, with you if you still do not have it, I suggest that you register a web mail account identified exclusively for your power inverter. The system will use it to send Mails to all the destination addresses that you report in the Mail Addresses field.
The System currently has a basic Event Handling, such as when the Main Energy is cut off and the installation works with Batteries in Back Up Mode, when the batteries change State, Stand By, Load, Discharge, etc., etc., etc.
Notwithstanding that, I am working on this to extend it to all types of Events that may also be Defined by the User. When it is well tested in my home, as many other modifications and extensions.
In the next revision of the Version the system will notify you of a Main Energy Grid Cut or any other event defined as High Importance, as soon as it occurs and both you and your family outside your home will know what happened if you configure your Mail in the cell phone.
[Daily summary of energy balance]
In the current version if you check the check box, between 23:59:58 and 23:59:59 (depending on Internet conditions) the system will automatically send you the Mail with the daily information collected by the system. Shortly I intend to expand this info by adding very simple information, but useful for example the GRID Energy Values to Pay to the Local Company, Percentages per day of loads that have been supported by Real Effective Solar Production, Kg of Co2 by GRID energy use,  etc., etc ...
Then a couple of copies of my cell phone screen (two pages) to observe the information that the System communicates to me daily.

 
Okay. There are more things, but I get tired. This is all for now.
Sirs. I await your comments. Greetings to all.
