Starting current of the motor is huge, several times operating current,,while the panels are strictly current limited. You need a source of power at fairly high current - like a small battery - to get the pump started, then it should run off the panels (assuming pump power <= panel''s actual output power)
You might be facing a low voltage problem. Low Voltage in Solar panels often happens due to the panel not getting sufficient light. Shading, Dirt Buildup, and Environment often cause this. Other things that cause low voltage are faulty wiring, degraded panel, and low-quality equipment.
The higher the temperature, the lower will be the power output. Adding more modules in series, and therefore increasing the string voltage, will eliminate this problem. Also, make sure that there’s sufficient air circulation beneath the panels and that this open space is not blocked in any way.
When shading occurs under load, the power produced by the solar panel drops because the panel cannot produce its total energy capacity. The load has little to do with the decline because the power level from the panel was already low. Is the Temperature Playing a role in Load Capacity?
For undervoltage errors, an inverter repairer will need to check the condition of the battery and replace it if necessary. If the battery is in good condition, they check the panel’s connections to ensure that they are secure and not damaged.
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.
If your solar panel or array drops volts when under a load, the problem may be any number of issues. The best place to start is as follows: Start with your testing equipment. Make sure it is working correctly and that the connections during testing are good.

Solar array mounted on a rooftop. A solar panel is a device that converts sunlight into electricity by using photovoltaic (PV) cells. PV cells are made of materials that produce excited electrons when exposed to light. These electrons flow through a circuit and produce direct current (DC) electricity, which can be used to power various devices or be stored in batteries.
Solar panels are manufactured with specific voltage and power output ratings, but slight variations can occur during production. These tolerances typically range between +/- 3% and +/- 5% of the rated output. Solar Panel Efficiency. The efficiency of a solar cell is gauged by dividing its electrical power output by the power of the incoming light. N-type panels, being more efficient …

As you can see in the image above, when 50% of the cell is blocked from sunlight, its current is cut in half s voltage on the other hand stays the same.. When it''s completely blocked from sunlight, the shaded cell doesn''t have any outputs. However, as mentioned above, a solar panel is a series connection of solar cells (ex: 36 cells) and is not a …
Undervoltage faults occur when the DC bus voltage falls below the inverter''s undervoltage detection value.
