Need starting ampere load and running amperes


The inverter would have to be motor rated as the starting torque is much higher than the running watts required. Starting at 240v is around 5 amps, running about 2a at most.

Hi, I have KEB 07.f5.c1b-3b0a inverter. I just got


Via Combivis, write a value of -4 to Fr.01. This will set all parameters back to the factory default values.

Then download your backup parameter file.

I have a coleman powermate pmp400-t inverter 400w/800w will it power a sump pump? I tried it and it beeped and the fault light came on


Hello, the answer is no. This inverter will work with a pump that below or about 400 watts power for operation. I notice it says that the inverter 400w/800w. The 800 watts is the surge required to get an electric motor to run. On a single phase motor (120 AC) and it take 4 amperes to operator this motor. But to start the it will 12 amperes to start it. This is one reason why on a lot of electrical motors there will be a big tube or can, this is the starting capacitor, it stores energy in form of current (amperes) to drop across the windings of the motor when it starts. If some electric motors didn't have this capacitor. The most likely scenario would be tripping a breaker because it drawing to much current.


Now, for you problem. Example of Power and the unit of the formula is V (volt), R (resistance) I (current) P (power) Ohm's states that :

f9ae53a99f2b2b6a74146fb04fb3ff73.png


Now Power would be stated: P = V times(x) I. Therefore in your case, if the pump at normal operation is drawing 4 amps of current for operation pumping water. The power factor would be 120 V AC (house voltage) times (X) I (current) which 4 amps. So here is what you have: P = 120 X 4 equal= 480 watts.

Therefore, your inverter will not work because it operating at 80 watts more than the power inverter can deliver which is 400 Watts.



If you need to purchase a new power inverter, remember always take into account the Amperes required for operation. Just by the simple Ohm's Formula. Best of Luck. GB....stewbison

Pavilion DV3 not working on a car charger That is working flawlessly on other hp nc6400 laptop they both work great on the 220v standard adapter! Why isnt my laptop charging?? Please help


Hi,

the 220 v power of cities has 25 Amper

has your inverter 25 A . of course not

so this is right that tow power sources have 220 VOLTS but the important matter for working

a device by power source is the out put AMPER plus output Voltage.


good luck

My 24v 1500w inverter cuts out when i use my 700w microwave?


Normal 0 MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman";} The starts up power for some appliances we use at home are sometimes higher than their actual power. For example a fridge will start with a power of 2 to 3kva then after start up it goes down to its normal power of 700va to 1kva .
Your inverter will continue to switch off if your if you battery is
  1. Low i.e. it is not fully charged
  2. Has a low ampere rating
The solution is to get a battery with a higher ampere rating like 200ampere/hour and above, connect it in parallel to the other battery i.e. the positive terminal to the positive terminal, the negative terminal to the negative terminal. This additional will accommodate the excess power needed for the microwave to start up.

Note that it is not advisable, to use this type of power appliance on a small inverter .Use a battery with the same volt rating i.e. a if you use a 24volts battery get another 24volts battery with a higher ampere rating

I am looking at the same problem/solution


Ok, Heres the deal. A gel cell battery is 7.2 Ampere hrs, so to get 14,4 Ampere hours you would need two batteries connected in parallel. A F&P machine such as mine consumes around 60 Watts of power. Using Ohms law we get W= IxE or Watts = volts X amps[or amperes = watts / volts] so that a 60 Watt machine has a current draw of 60/110< =0.55A so that a 14.4 A/hr battery will run this machine for around 20hrs (allowing a residual charge of 25%)
