Re: Using the battery as an emergency supply

Kiev, I installed a domestic 1840wp grid solar panels tied to the utility supplier. I export all unconsumed generated power to the grid and import from the grid when consumption exceeds generated and at night. On average I generate what I consume especially in summer. I am now waiting for a storage ...

Re: Using the battery as an emergency supply

Aerowhatt, Now the solutions are coming in fast. Thank you for you suggesting to charge a deep cycle battery using the high power dc to dc converter of the iMiev. From your figures it is much more efficient, even though the auxiliaries consume 500w/hr. (So this is the reason the fuel gauge depleates...

Re: Using the battery as an emergency supply

Kiev, That is a very interesting option. I would say it should suffice for power as it would consume two notches on the fuel meter and give me 24 hour of autonomy. I need around 120w/hr. I would need to find a 230 v ac at 50 hz one so as not to burn out my equipment. Most of it is rated at 220 volts...

Re: Using the battery as an emergency supply

Kiev,

Thank you for your suggestion. I would need to find an inverter which has 340v dc input to 230v ac output. I have never seen one on ebay. Any suggestions?

Re: Using the battery as an emergency supply

Thank you both for your replies. Which mirror each other. It all started out from the fact that Mitshubishi has produced for the Japanese market after the zunami to give distributed power during the emergency. However they never produced it for other markets. Thus my idea is a non starter. Thank you...

Using the battery as an emergency supply

Since my last post I carried out a test to see how efficient it is to use the auxiliary battery to generate a supply in the field. In my case as a supply for my ham radio activity. I attached a car head lamp to the auxiliary battery and measured the voltage, current, and power in watts. I turned on ...

Re: Using the battery as an emergency supply

Before I took the measurement I allowed the load on until the first used notch was used up.

Do you have any recommendations on how I can measure the consumption more accurately?
