120volt battery bank
How do you expect to you wire 6x 40v 10a panels to achieve 240v 60a? You have some studying to do. Beware, voltage over 30v can kill. typically, pv output should go into a solar charge controller (scc), which will convert it to nominal useable output for a 12, 24, or 48 volt system (battery chemistry also need be taken into account when choosing a charger).

6 FAQs about [Solar power bank has no voltage output]
What are some common problems with zero voltage solar panels?
Common problems with zero voltage include a faulty inverter or charge controller, a solar panel that has failed, shading, increased temperature, hotspots in a solar panel, poor connection or faulty wiring, and delamination caused by water entering one of the solar panels. We will look at the most common scenarios where PV systems fail:
Do solar panels have no voltage?
No Voltage From Solar Panel (Solutions) - Solar Panel Installation, Mounting, Settings, and Repair. It can be frustrating to find you don’t have voltage from your solar panels, but the potential problems are relatively straightforward to diagnose as there can only be a few issues that cause the lack of power.
What causes a solar panel to register no power?
These are actually common problems and there are ways you can fix them. A faulty inverter or charge controller are the most likely reasons for a solar panel to register no voltage. Other possible reasons for low to zero power are a damaged PV module, poor wiring, shading and temperature higher than the ideal operating range.
What causes a lack of voltage from solar panels?
Aside from the above, high temperatures, shading, panel damage, and faulty connections can cause a lack of voltage from solar panels. All electronic devices, including solar panels, operate far better at lower temperatures.
Why isn't my solar panel generating electricity?
A solar panel generates electricity from sunlight. If it doesn’t get sunlight, it won’t generate voltage. Environmental factors like shading, panel dirt, heat, and bad weather can prevent sunlight from reaching the panel, affecting its ability to generate electricity. In extreme cases or when there is low sunlight, the panel’s voltage can drop to zero. Another reason could be a faulty solar panel, which won’t create the desired voltage.
Why do solar panels have a low power output?
Conducting a bi-annual survey of the installation site is a good idea. If shading is not an issue, most likely it will be the higher than normal operating temperature of the solar panels. It has been scientifically proven that the voltage drop rises with the rise in temperature. The higher the temperature, the lower will be the power output.
