There are three types of inverters available: the string inverter, the power optimizer, and the micro-inverter. You would only need one inverter when using string or power optimizers, but using micro-inverters doesn’t require a standalone one. .
You would need to purchase an inverter that matches the output of your solar array, so if you have a 6000W (6kW) system, your inverter. .
You can connect inverters in parallel to double the wattage (power) or in series to increase the voltage. You could do this if you have several smaller inverters that you want to connect. [pdf]

Here are some charts on what size solar panel you need to charge 12v and 24v 200ah lead acid or lithium (LiFePO4) battery. .
The maximum charging current for a 200Ah lithium battery is usually 100A and the ideal charging current for a lead-acid or AGM battery is 50A. Charging your battery at a higher. To charge a 200Ah battery, use four 120W solar panels in a 12V system. For a 24V system, you will need two 200W panels. Charging time depends on sunlight and panel efficiency. Accurate calculations lead to effective and reliable charging with solar energy. [pdf]
