Powertech MP3129 is not working. when connected to the solar panels and and batteries there is nothing. no digital readings. blank screen. Panels are putting out 19 volts and the batteries 13 volts.

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.

check with you installer but the battery should be running the house and allowing the solar system to work as well

No. It will work in with diffused light too. Some sensitive ones will generate voltage even at moon-light.
Electro help

Solar panels are typically rated at .3 volts per cell. These cells are connected in series until they add up to 12 volts,24 volts or 36 volts depending on the solar system. The more cells you have the higher the charge rate of the batteries connected to the system. The DC voltage from the cells are used to charge the batteries then the voltage from the batteries is used to drive a DC to AC- convertor which is the power used by your home. The more cells connected the quicker it will charge the batteries and the more batteries connected the more power the solar system can provide.

G'day Peter, if i can get a postal address or if you have a fax i will photo copy my manual and send it out to you. I am in Melbourne.

cheers, Lance
