But man and lady are sure happy !

Probably not married> 

I am interested in balancing the load on my 220v inverter from my 110v fridge.

While we are talking about load balancing, has anyone used or had experience with a 220v to 110v step down unit?

example

I've never seen it before.
It's continuous 1200W and 3kW maximum.  Only weighs 13.4  pounds.

What is in it and how does it work ?

3kW for 30 minutes sounds like it might be a real transformer in it.
Almost too cheap even for 1200W if it is a transformer.

Their advert pictures are kind of funny.  The box is shown on the table where the man and woman are working, like in the kitchen but the box is not doing anything and the meter is at zero.   But man and lady are sure happy !

Not all inverters are created equal.

I use two AIMS 6000w 48v inverters (Sigineer equivalent) 220v split phase

They are rated for overload as follows:
110%< load >125% 14 minutes  125%< load >150% 1 minutes  150%< load >300% 20 seconds

It is also important to load balance the 110v legs. If you have too much on one 110v leg, you can easily excede the limits on one leg.

I've noticed led lights flicker when my Outback inverter use or drops utilitypower...and when the freezer kicks on.  Large loads and power transfer.  Must be ignored or it will drive you crazy!

BBMT ?

from a few posts back
First we need to name this potential new product. I would suggest BBMT (Barry's Better Mouse Trap).

MNGP2  which is CAN

Completely different than the MNGP

Sooo It would make sense if we wish to use BBMT on classic 150 or Hawksbay, it should have both modbus and Can capabilities.

BBMT ?

Lead Acid (Sealed and flooded) / Re: Float current degradation

Last post by Barry Fields - May 16, 2024, 03:37:00 PM

Answers from East Penn

(1) Assuming a reasonable absorb time, once given a float voltage of 2.35 vpc, the float current should eventually stabilize @ approx. 450ma (for a very healthy battery). SOC=100%  TRUE? True


(2) If the stabilized float current is above 450ma it is an indication that the battery no longer has 100% of its original AH capacity. TRUE?

              The stabilizing current of the GC10 will increase as the battery ages. When the battery is new the stabilizing current will be 450mA. Unfortunately, the rate at which the current increase over time is not linear. The rate of stabilizing current increase is affected by ambient temperature and usage (# of cycles & DoD of each cycle). Taking specific gravity readings is the best way to verify the batteries are fully charged. Page 5 of the attached I&O manual details the ratio of specific gravity to SOC (state of charge).


(3) Is it possible to assign approximate numbers to question (2) ?  IE 600ma = 95%AH capacity  900ma = 90% AH capacity

              Unfortunately, the charge current can not be used to determine SOC of the battery for reasons stated in the above response. Specific gravity reading are the only way to get an accurate SOC.


(4) In a parallel battery bank, the bank with reduced AH capacity would achieve 100%SOC (with reduced capacity). ?

              Correct


(5) That battery would contribute less amperage to the total bank discharge currents and probably require more current in the charge cycle. (efficiency degradation)

              Correct

We were having issues with Mymidnite at that time. Have the readings come back?
