The 1.5kva 12v inverter and solar energy system are suitable for low-medium energy users, typically found in households and businesses. This system size is based on the capacity of the inverter.

The 1.5kva 24v inverter is usually connected to two 12v batteries. It can also be connected to 4 batteries and multiples of two, however, it would take double the usual time to charge those batteries to full capacity because the inverter’s charging current is optimally set for two batteries.

The inverter’s charging time could be augmented by having more solar panels and a quality MPPT solar charge controller.

The 1.5kva inverter & solar system can carry lighting systems, TVs, sound systems, computers, and small to medium-sized fridges. Of course, these appliances are subject to the maximum output capacity of the inverter.

Though a 1.5kva 24v inverter running on two 220ah batteries can carry a fridge or freezer, the battery will drain out faster due to the higher energy consumption of the cooling appliances. It is best to have these on a higher system size like the 3.5kva or 4kva 48v system which runs on four batteries.

How long the 1.5kva system will last in hours depends on the amount of load it carries.

The size and number of solar panels for this type of inverter system depends on the energy requirements of the user. A PWM solar charge controller can be used for this system size, but it cannot be compared to the fast charging abilities of the MPPT solar charge controller.
