Explorers:
A man lives on a 10th floor of some building. Every morning he takes the elevator to the ground floor to go shopping for groceries.

When he comes back, he takes the elevator to the 7th floor and continues by stairs to reach his apartment on the 10th floor.

Why?


Part of exercise?

said it before..get a pro near you to help you.do an energy audit
if you cant get a pro..
u can list all the loads you power the inverter with, and state how many hours on the average you power them.
also confirm on the average how many hrs of phcn you get daily.

eg freezer 140w...runs for 6hrs daily etc do same for all the loads in ur house
confirm the exact specs of your inverter and charging current if known eg 24v 2.5kva sukam inverter etc.

am almost certain your present btteries are dead, and you would hv to discard/sell them off soon
you have to reduce your load and or increase your battery bank to 4 or more...if u want ur new /future batteries to perform any better

earthrealm:
wow, all this load on 2 x 12v 200ah battery?!!!!.
you overloaded the battries...thats why they failed prematurely, batteries last longer if you dont drain them below 30% dod [depth of dischARGE], by the time the inverter starts beeping, its already too late, as the draw is below 30% dod.
if you still want to continue using inverters and hv the batts last longer...you need to do a load analysis & optimization

for eg 2 x 12v 200ah batt contains 4800wh
assuming 90% efficeincy this leaves you with 4320wh or 4300wh approx
@ 50% dod = 2150wh.
for ease of calculation lets assume 2000wh
so u can only power a
200w load for 10hrs
400w load for 5hrs
100w load for 20hrs etc

the load u listed is way above 400w
36'' tv shud be about 80watts, if led, n 180watts if lcd...and you have 2
washing machine is between 400w to 1000w
fridge is between 80w to 140w depending on size
laptop is 65w
fan is 80w
light bulbs...u didnt state..

thus you can see that u severly overloaded the system leading to its sudden and premature failure
