Morning PowerForum 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 . Jannie
