    I am a newbie when it comes to Solar , Battery back up and Inverteres .
    With Eskom being what it is , i am starting to look into a smallish battery back up system .

    I have one at the moment for my fishroom - A OmniPower Caddy Power Backup System with 100Ah Gel Battery, Modified Sine Wave, 1000W Inverter/Charger . It works perfectly for my fishroom .

    Now i want to setup another one for my TV , TV Box , WIFI and some spotlights outside .

    I bought a FIVE STAR 1000VA/800W PURE SINE WAVE HYBRID INVERTER WITH BUILT-IN 40 AMP MPPT .

    I will be setting it up as follows :

    Inverter : Connected to AC power . AC power out to a DB box with various breakers for TV section , Fish room and Outdoor lights .

    Batteries : 5 x 100AH Gel batteries ( 12V 500AH system)

    Battery Positives will all run to a central bus bar aswell as the Negatives will run to their own bus bar(all cables will be of the same length 1m) . See attached picture .


    Where do i need to put in breakers/cut offs/fuses and also sizes ?
    What gauge wires do i need to run to the various components ?


    Batteries - Do i need to have 1 fuse per battery or can i only use a fuse/cut off between bus bar and inverter ? 
    What size fuses/cut off will be needed ?
    What size wire will i need to run from the battery to the bus bar (1m lenght) and also wire size from bus bar to Inverter ?

    Inverter - Do i need a Cut off/Breaker between the AC in and the Inverter ? If yes what size ?

    Load - 500w
    TV - 150w
    TV Box - 50w
    WIFI - 50w
    Outdoor lights -100w (10 x 10w LED Spotlights)
    Fan in the summer - 150w

    Only used when there is Load Shedding .

    Thanking you in advance .
