The 3.5kva and 4kva 48v solar installation is the most popular demand for many looking for more power to cater to home and office appliances such as fridges, freezers, air conditioners (AC), photocopiers machines, pumping machines, etc, in addition to televisions, fans, computers & lighting points.
Please note that the examples of appliances given above is subject to the recommended maximum output capacity of the inverter. The maximum output an inverter has differs according to brand.
The 3.5kva and 4kva solar installation draws its title from the capacity of the inverter. It means the inverter can carry loads up to its recommended maximum capacity and it can draw the same amount of power from the batteries.
This type of 48-volt system, in contrast to the 24v system, comes standard with 4 units of 220ah tubular batteries, or 200ah dry cell batteries, or 48v lithium battery.
It therefore means that how long a 3.5kva and 4kva inverter/solar energy system will last depends on the load it carries and the state of charge and life of the battery.
This system size comes standard with a minimum of 9 320w solar panels. The number of solar panels can be more, depending on the energy needs of the customer and the size of the panels.
It is highly recommended that an MPPT solar charge controller be used for the installation of the 4kva and 3.5kva solar energy systems. Though in theory, a PWM controller “will work”, it is much less efficient in converting solar energy from solar panels, hence, the loss in solar power negates its cheaper price tag.
