You need to precharge any inverter 2000W or above. Smaller inverters have smaller capacitors that charge even quicker than those in larger inverters. We'll keep things quick and simple so you can get your inverter up and running with minimal stress! Want to learn more about inverters? Our page on campervan inverters takes a look. . When you initially send 12v power to your inverter it takes a second (or fraction of) to energize everything. This sounds like something that should. . If you have a SMART4 / SMART5 or HOME battery, please consult the manual on the startup procedure to make use of the built in pre-charge system. I have a 30 ohm resistor which I plan to connect to a negative terminal of my battery buss bar and touch the other end to the negative lead coming out of the inverter (currently disconnected from. . And yes, if your MPPT is enabled it will pre-charge the capacitors in the inverter. Also will show you how and why to properly size your. .
