The 3.5kva and 4kva 48volts inverter and solar energy system is the popular demand for many looking for more power to carry their home and office appliances such as fridges, freezers, air conditioners (AC), photocopiers machines, pumping machines, etc, in addition to televisions, fans, computers & lighting points, etc, for a longer time.
Though the 3.5kva and 4kva systems can carry more load than their 1.5 to 2.5kva predecessors, the maximum watts drawn from it at any given time should be subject to the recommended maximum output capacity of the inverter.
Although KVA simply means 1,000-volt amps and translates to 1,000 watts (1000w), the 3.5kva/4kva might not produce 3,500watts or 4,000w respectively. The rated maximum output of an inverter differs according to its brand name. This applies to all categories of inverters.
The 3.5kva and 4kva 48v solar energy system gets its title from the capacity of the inverter. It simply means the inverter can carry loads up to its recommended maximum capacity and it can draw the same amount of power from the batteries.
A 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.
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 mono solar panels. The number of solar panels can be more, depending on the energy needs of the customer.
Due to the larger battery size and load, it is highly recommended that an MPPT solar charge controller be used for the installation Though a PWM solar charge controller “will work”, it is much less efficient in converting solar energy received by the solar panels, and the loss in solar power will inadvertently negate its cheap cost.
