About How to remove the photovoltaic inverter battery
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.

If the inverter has no load and disconnected for a few minutes, the inrush should not be a problem. With battery it is good practice to disconnect the negative first and connect the negative last. Maybe you need a buss bar to have multiple connections that do not interfere with each other.
Step-by-Step Guide. Turn Off All Devices: Before starting, turn off the solar inverter and any other devices connected to the system.; Disconnect the Charge Controller: Locate the charge controller and disconnect it first.This device manages power between the battery and solar panel. Label the Cables: Use labels or tape to mark the cables for easy identification during reassembly.
The inverter is disconnected from the electrical grid by an AC disconnect. It can be a freestanding switch or a breaker on a service panel, and it is typically placed on the wall between the inverter and utility meter in a solar PV system. Switches known as DC disconnects can stop the flow of DC (direct current).
Make sure any lead-acid battery is fully charged before disconnecting it. Because AGM's have pure lead plates they have less then 0.25% C per day of self discharge so going three to five months should not be a problem.

6 FAQs about [How to remove the photovoltaic inverter battery]
How do I Disconnect a solar inverter?
For most installations, you will need to turn off the AC disconnect switch from the inverter to the main electrical panel and then the DC disconnect switch from the PV array to the combiner box (if available) or inverter input.
Can You disconnect solar panels before leaving an inverter?
Although solar system outputs prior to leaving an inverter are low voltage, caution and safety are still paramount. Before attempting to disconnect the solar panels, isolate all AC or DC disconnect switches or fuses in the circuit. Try to make the disconnection at dusk, if at all possible when the panel output is low.
How do you disconnect a solar power system?
Solar panels should be disconnected by first turning the solar disconnects to the off position, both on the DC and AC sides. The wiring connections between panels should then be removed. There can be several reasons to disconnect a solar power system, the most common being for maintenance or repair purposes.
Should you remove solar panels when not generating power?
Cover the Solar Panel: Even though you should disconnect solar panels at hours when they are not generating power, you should always try to cover them with opaque cloths before removing them. Doing this will ensure no solar generation, making it safer to disconnect the modules.
How do I disconnect battery power?
To disconnect battery power, first turn off the breaker or switch for the solar array. Then, turn off the breaker from the + charger output to the + battery bank bus. To reconnect, reverse the process: turn on the breaker from the + charger output to the + battery bank bus first, then turn on the breaker or switch for the solar array.
Can a battery inverter cause an inrush?
If the inverter has no load and disconnected for a few minutes, the inrush should not be a problem. With battery it is good practice to disconnect the negative first and connect the negative last. Maybe you need a buss bar to have multiple connections that do not interfere with each other. I like fuses on DC circuits.
