Tips to know if power inverter on off-grid application is under-rated since 95% of inverters of this kind is already out in the market... *** If the capacity is higher than 1000watts and yet the input voltage is only 12Vdc. Why?..... Answer: Power formula is... Watts = voltage x current or.. Current=watts÷voltage So, beware of these brand name TBE, SUOER...etc. Example: TBE, 3000watts 12vdc to 220Vac If these is true.... then, the current @ battery side at full load will be.... I=P/V..=3000/12.. = 250 Ampere Imagine, the size of conductor wire does it need...? ? ? ? ?
