Here are a few 2400W inverter options that can be linked to a DB (distribution board): The Voltronic Power Voltronic Axpert V Off-grid Inverter 5KW With 2400W Pwm costs R8538.75. This inverter has a maximum output of 2400W which meets your needs. It also has inputs that can be wired directly to a battery bank and outputs that can be connected to a DB via wiring. The Mecer Axpert Maximum 8000W Pure Sine Wave Inverter costs R20389. Though it has a higher maximum output than needed, it would provide a safe overhead and also allows for scale-up later if required. Like the above option, it has wiring terminals that allow connection to batteries and a DB. The Kodak Solar Off-grid Inverter 10KW 48V SEHM12 costs R19676.58. Again it offers a higher output capability but at a slightly lower price than the Mecer option. It is also designed for off-grid/backup power applications and integrates inputs and outputs for battery and AC wiring connections. Apologies that I do not have access to the entire PriceCheck catalogue. Please let me know if you need any other details on these suggested inverter options or have additional requirements to consider. I'm happy to discuss further.
