    Set up a small system for a local guy... He seems to think the battery is draining too quickly

    An inverter is just a converter, not an energy producer. We should offer enough batteries before it can drive the electrical appliances.

    VERY small off grid solar system do I need to use a breaker/fuse?

    Your 8 lights is dc 12V input ?or ac 110V input,I have not seen an inverter in your system

    Set up a small system for a local guy... He seems to think the battery is draining too quickly

    100Ah battery can not run full 3000W inverter , and once he plugs in a high power appliance,such as fridge, microwave oven,etc, his battery will fall down very fast..So please suggest him to add more pcs battery.

    Inverter in RV Electrical System

    I guess he said 700W microwave actual starting power is not 700W ,but 2 times higher,so 1500W inverter is good for you, and 2000W inverter is better for you

    Auto transfer switch needed

    1100W microwave usually starting power is about 2200W, so renogy 3000W should be enough Low voltage protection,please check below 1.check the cable connections and ensure the cable size are sufficient,the shorter the better,especially for the high power appliance. 2.one or some of batteries in...

    In need of help!

    In general, users who purchase a 4000W inverter are looking to start high-power appliances such as electric saws, motors, etc. Therefore, the seller will suggest that you choose to equip them with a 400AH battery or bigger. But if you only run lights or TV by the 4000w inverter, two 50AH...

    Isn't a 3000W inverter on 12V really pushing it as far as current?

    Because the market demand for 12V inverters is higher than that for 24V inverters

    Battery Cable size

    For the 300A current, 1 awg within 3ft 3/0 awg within 6ft 4/0 awg if you need 10ft.

    120 v to 120 v inverter Switch

    I guess you need a power inverter with ac transfer switch,such as AIMS Power PWRIX200012SUL 2000 Watt Pure Sine Inverter with Transfer Switch 12 VDC to 120 VAC ETL Listed

    Yet another inverter question

    Usually,small inverter no load current is smaller than bigger inverter,for example,1000W pure sine wave inverter noload current is about 0.5A, but 2000W pure sine wave inverter no load current is about 1.5-2.5A.So if your appliance is small, you can change another 1000W pure sine wave inverter

    Continuous power vs surge power for the fuse and the wire sizing?

    Only read the continuous power when we choose inverter, for your 2000W inverter, 200amp fuse is OK. For the cables, please choose short and thick cable as you can ,in order to pass high current appliance. 3AWG within 3 ft, 0AWG within 6ft, the thicker the better

    LiFePo4 12v 100ah x2 in parallel fuse size?

    BMS Low Voltage shutdown is about 10.5-11V,usually higher than inverter low voltage shutdown, once battery goes to protection, the inverter will cut off at once,because no dc power feed in to it.

    Help sizing an inverter - downgrading from 2000W to 1000W with an AC fridge

    Killawatt meter shows the fridge uses 50-75W when running and about 600-800W startup, it means your fridge max power is 800W,so 1000W pure sine wave inverter is enough for you. The fridge actual starting power is about 10 times higher than rated power,so means 75*10=750W. Maybe you can try...

    LiFePo4 12v 100ah x2 in parallel fuse size?

    If you are asking the fuse between battery and inverter,for your 1000W inverter,its max current is 100A,so I suggest you to install a 100A fuse between inverter and battery, and install the fuse in the middle of positive cable ( red one).
