WILL THIS INVERTER WORK FOR ME AND HOW MANY HOURS WILL IT LAST???
There is a lot of confusion around what the inverter size and battery Ah means in a backup system, so we've made it simple, here is a general breakdown to easily understand the consumption and load for a basic inverter system-
Your Inverter size is the maximum power you can draw at any given time, example, with our 2.4kva inverter you can peak at 1.8kW before your inverter will switch off to ensure it doesn't overload and burn out. Though it is not ideal to run an inverter at its max capacity for too long, it is important to have this peak ability when your devices/appliances switch on or power up components for cooling/heating etc.
The amount of battery capacity you add determines your backup time, also remember that lead batteries should never be discharged to 0% discharge. For example, our sealed maintenance free AGM batteries are 130Ah (20Hr rating) meaning they produce 1.64kW (130A x 12.6V) backup power when fully charged, I recommend that one should not discharge AGM batteries any lower than 40%, meaning you get roughly 950Watts (60% of 1.64kW) of usable backup power. Where your conventional lead acid 12V 100Ah(20Hr rating) battery produces 1.2kW backup which ideally you don't want to discharge lower than 60%, will only give you around 500Watts (40% of 1.2kW) usable capacity.
To summarize all of this, running a 200Watt load (tv, chargers, fibre, router, DSTV is roughly 200Wh) with a USABLE battery capacity of 1000Watts will last you 5 hours!
We hope this helps a few of you :) !
