You can connect almost any appliance to an inverter, with a few practical exceptions. In practice you must be careful with equipment that consumes a lot of power, such as electrical heaters or air conditioner. While the inverter itself has no problems with these loads, the battery capacity is often too limited for long-term usage of these loads. Appliances that are only used for a limited time period, such as washing machines, driers or a small hotplate, should be fine as long as the battery. Keep in mind that heavy users such as engines, pumps, air conditioner and fridges have a starting current that is between 5 to 12 times higher than the nominal absorbed capacity. The inverter has to be able to supply accordingly. BELTTT inverters are developed to provide high peak currents.
