The answer is no, off grid solar power plant require batteries to store electricity. If the grid power isn't available and batteries are out of equation too.
[pdf] MPPT optimizes the voltage at which panels operate, ensuring that even under less than perfect conditions (cloudy skies, dusk, or dawn), the system performance remains at peak.
[pdf] 4 Steps to Properly Ground Your Solar InverterStep 1: Run a Properly Sized Grounding Electrode Conductor The grounding conductor between the inverter and the grounding electrode system should be #6 AWG or larger bare copper wire. . Step 2: Connect to Grounding Electrodes . Step 3: Establish Continuity . Step 4: Label All Connections .
[pdf] You'll generally need an inverter that's 75% as big as your solar panel system's kilowatt-peak (kWp), which is how much solar energy it produces at standard test conditions.
[pdf] Disconnect the AC and DC switchesInspect your system to check if it has a disconnect switch. If not, place a reflecting or opaque surface over the solar panels.Verify that the voltage is zero by using a voltmeter or multimeter.Unplug the wires. This is simple using MC4 connectors, or you may use a socket wrench.If necessary, take out the bolts and clamping mechanisms.
[pdf] String inverters convert DC power from “strings” of PV modules to AC and are designed to be modular and scalable. Smaller string inverters may have as few as one input, with one PV string per input.
