    My 24v LiFePO4 280ah off-grid preliminary design

    I've updated the SSC, removed the 250A fuse (I assume the single 300A fuse would be fine). Image: Version 1.1

    My 24v LiFePO4 280ah off-grid preliminary design

    Thanks all... Does the wire sizes looks good? @MisterSandals I'll redesign the solar panel - SCC part of this and add an updated design.

    MPPT, BMS and Inverter wiring question

    @indalecio I think I maybe able to use the load of the solar charge controller to activate/deactivate a relay to control the inverter. This way, when the bat level is low, inverter will be turned off...

    MPPT, BMS and Inverter wiring question

    Hmm... The solar charge controller can output only 40amps. Can the inverter run with that power? Is the design above commonly used by everybody? I'm not comfortable powering the inverter from the solar charge controller...

    Hi all... I'm a newbie here and I'm planing to build an off-grid system for my home. So far I'm planning on using a DIY LiFePO4 battery 280ah 24v (From Amy). Referring to the sketch attached (ignore any wire sizes, switches or fuses) I have a question. Assuming it's day time (charge controller...
