For the resistor, this means high reliability with long lifetime, high voltage-withstand capability and high accuracy. Panasonic has a variety of resistor families that can be employed in solar inverters applications.
High voltage system in PV inverters operation requires a safe insulation resistance between the PV panel to ground. A poor insulation resistance less than 1 MΩ leads to a high leakage current (about 1 mA), which not only will damages the system but also injure the user.
Pic taken when used it for tests of solar panels (Voc ~ 48 V). Take care - Not shows in the pic - the bulbs are in the air away from wooden supports. Anywhere from 5 - 50 ohms 1W+ should be fine. It''s not critical. I use a 30 ohm 300 watt resistor in a 100v system. For a 48v system about six ohms as suggested previously might be about right.
A solar inverter (also called a photovoltaic or PV inverter) converts direct current (DC) into alternating current (AC) and is widely used in solar photovoltaic power generation systems. Solar inverters available today are generally divided into three types: central inverters, string inverters and micro-inverters.
