- DIAGNOSIS
- Does not compute. I need at least one load (12V DC or 120V AC) to size your system. Beep boop!
- Battery Bank: You need over 600Ah. Consider switching to Lithium instead.
- Battery Bank: You need over 600Ah and that's over my capacity. Beep Boop!
- Battery Bank: You need over 600Ah and that's over my capacity. Beep Boop!
- Battery Bank: Consider upgrading to a larger battery bank or adjusting your needs in 12V DC & 120V AC tables.
- SOLAR: The selected solar delivers too much current for this battery bank. Choose a smaller solar or upgrade the battery bank.
- Alternator: The selected charger delivers too much current for this battery bank. Choose a smaller charger or upgrade the battery bank.
- Alternator: The selected charger is too big for your vehicle's alternator ("small" VS "regular" VS "Heavy-Duty/Dual"). Choose a smaller alternator charger.
- Shore: The selected charger delivers too much current for your battery bank. Choose a smaller charger or upgrade the battery bank.
- Inverter: You need over 3000W and the wiring diagram doesn't support that. Beep Boop! Make sure to only check loads that'll run simultaneously under "inv" column in "120V ac" table.
- Inverter: Consider choosing a smaller inverter or upgrading your battery bank. Your autonomy is very short with the actual selections.
- Inverter: The selected inverter draw too much current for this battery bank. choose a smaller inverter or upgrade the battery bank.
- Inverter: Consider upgrading to a larger inverter or adjusting your needs in the 120V AC table.
- Heads up! We had to adjust the battery bank, because we found no equivalent following your new selection.
- SHORE CHARGER: not needed with inverter/charger.
2- Size Your Wires, Fuses & Breakers
+ Wire Lengths & Terminals Calculator
Appropriate wire gauge (AWG) varies with length & load and, therefore, is unique to each installation. Our wiring diagram automatically sizes the wire gauge, fuses & breakers to ensure that your own system is safe and performs as it should. Bonus: it also calculates all the wire lengths & terminals that you'll need by type/gauge, which will make STEP 3 (customize your items list) super easy to complete. No other diagram does this!
- With the inputs you entered, we recommend downloading the HIGH-POWER wiring diagram.
