Hi, just had a Solar Lord 1.5KW inverter/8 panel system installed. Would like to know what all the different read outs on the inverter box screen mean. Wasn't left with any instruction book etc. Readout changes every 10 seconds or so and gives me Pac reading and other things. Can you help

Yes, it is possible to connect an FBI2000W inverter to solar panels. In fact, inverters are an important component of solar power systems, as they convert the direct current (DC) electricity generated by solar panels into alternating current (AC) electricity that can be used to power homes and businesses.
To connect the FBI2000W inverter to solar panels, you will need to:

1. Install the solar panels on your roof or other suitable location and connect them in a series or parallel configuration to achieve the desired voltage and current output.
2. Install a charge controller between the solar panels and the inverter to regulate the flow of electricity and prevent overcharging of the battery bank.
3. Connect the output of the charge controller to the input of the FBI2000W inverter using appropriate wiring and connectors.
4. Connect the output of the inverter to your home or business electrical system, following all relevant electrical codes and safety guidelines.

It is important to note that connecting solar panels to an inverter can be a complex process that requires specialized knowledge and expertise. It is recommended that you consult with a professional installer or electrician who can help ensure that your system is properly designed, installed, and configured for optimal performance and safety.

First, I'm not a Sungrow representative.
* Contact your local solar vendor or contact Sungrow;

* Normaly after a PV install, there should have been a representative from the solar company (local rep) to walk you through the system features and have your internet solar monitor up and running. This app will collect all your solar data (very technical) and convert it to a "user friendly" display of power your panels and inverter(s) are producing.

I like to ask, is the voltage from the solar panel messure with some load connected or is open circuit, normally solar panels produce high voltage than the working system, the reasson for that is to have Amperes in of to charge the batery, these is related to the size and power generated by the panel.
No need a resistor or in any case use a voltage regulator to prevent over charge.

Hello Phil, what is the size of your solar panel? This pump draws 17 watts so, your panel must be 17 watts or greater. Remember a solar panel only puts out full power when in direct sunlight and facing the sun directly. You can read 21 volts but your amperage may not be full and this is why your pump is not running, not enough amps. I would recommend a minimum of a 20 watt panel.

The inverter will only make AC at a rate per the current and voltage being supplied by the solar panels. The panel outputs need to be checked and compared to the panels that are working correctly.

It certainly sounds as if there is a power distribution problem from the panels supplying the 3100 W average output inverter. It can be anything from a corroded terminal to a damaged umbilical or anything in between.
A bad ground for the inverter will also limit output. It may read resistance / continuity but can not carry the amount of current needed to produce 3100 W output. Given it has only been 5 days the problem should not be hard to isolate and find.
I had a similar problem arise quite recently with an 18 panel system and the problem ended up being corrosion on a terminal block connection. Cleaned up the terminals and reconnected everything with a 2155W difference from the original output on a 3200W inverter system.

Thanks for using FixYa.

the solar panel is just to charge your inverter,if it is charging and the inverter is on it will drain the current the solar panel is supplying to the batteries,this makes it look like it is not charging ,so i advice you to switch off you inverter when charging it,get another set of batteries connected to your solar panel then charge both, let them be separated so that the new one is not in use so that when solar is out you can switch to the other set of batteries

are your inverters rated at 60 cycle full sinusoidal wave form or 60 cycle square wave. while both will be tolerated in a transformer, the square wave tends to heat up because it isn't a sine wave. the peaks of a standard sine wave are cut off if observed on an oscilloscope.

Solar panels come in different ranges of wattages.Add up the wattage of different solar panels you get e.g. Ten 100W solar panels will give you a 1Kw solar system.
