First off, what you have is 0.9kva or 900va inverter, not 900kva like you stated.

Secondly, if your inverter batteries are draining that fast already, getting an inverter as large as 2.5kva will make it worse as the inverter will consume significant energy to power itself - it could be as much as 40w

Finally, your batteries may not be bad per se. You may just have an under-charging problem. Inverters with charging function do not charge batteries optimally.

Most times, they undercharge your batteries. Your lead acid batteries should bulk charge to 14.4-14.6v (full charge), then float down to 13.6v if left idle. But most inverters will charge to 13.5v, then stop charging and indicate as battery full when the battery isnt. The result is this sharp drop in voltage you currently experience and you wont get good backup time from the batteries. And if this situation continues, the batteries will begin to experience sulphation on the plates, leading to more damage.

What you need is an external charge to continue charging the batteries after the inverter stops its own charging. Also use a multimeter to get the voltage readings of your batteries while at it.

Meanwhile, where is your location? How many batteries do you have? And in what way are they connected - 12v or 24v?

0.9Kva 12v inverter with 440ah battery pack?

Obviously the batteries have been greatly undercharged all these while, and most likely are in the process of dying due to undercharging.

Anyone0455:
Definitely going for the 2.5kva upgrade and external charger controller
Should I go with hybrid or normal inverter

JoeSef0:
Hybrid please
Cost of a good mppt charge controller isn't cheap

Anyone0455:
The hybrid has mppt charge controller in it right?

bbally:
Yes

maklelemakukula:
Good day isiang, I want to make a purchase of >100kg from Alibaba, please what shipping agent do you usually use yourself that is reliable and affordable, and what's the average time it takes your goods to arrive

Anyone0455:
Is there any particular brand I should go for
Was thinking of buying the 2.5kva and charger controller separately before

i ant to ask

i will need to power

1 40 inches tv,
1 deep freezer,
1 1.5 hp inverter ac
1 industrial fan,
1 normal fan
2 laptop
1 decorder
i internet modern
16 bulbs , the low energy ones

do you think a Growatt SPF 6000 ES Hybrid 6kW 48V Big PV Input Inverter will be good

or do anyone have any good set up for atleast 10 hours off gride

SaintUlot:
You can plug individual appliance you want to save energy on to it and you can as well connect it to the house wiring, it is an energy saver as I said earlier, it reduces the energy consumption on your inverter, prepaid meter and generator from 25 - 50%.

Has anyone here stored Lifepo4 battery for 3 years?
If yes, what was the health of the battery (individual voltage measurement)?
I've only stored mine for 1 year at 50% soc and the cells were all sound when I returned.

One of my customers want to travel for 3 years.

My solar yield this January.

The heat this time of the year caused a significant drop in solar yield. Always remember to factor in the temperature coefficient when purchasing your solar panels so as to have a realistic yield estimate when you factor in the different temperatures we experience throughout the year.

10.2kw sms dual mppt
10.28kw panels (12x440w Jinko and 10x500w cworth)
18kwh cworth lifepo4 batteries ( 2x100ah and 1x150ah)
Solar Assistant on Raspberry pi5
Victron smart shunt 300a
Junktek shunt/battery monitor 100a

Achieved 100 percent off-grid status in January.

Take not, load does not factor in the 100wh consumed by the inverter itself (72kwh in 30days)

Peak continuous solar yield this month was 6,500kw i.e 63percent max yield

Peak cumulative load this month was 5.2kw

Max yield - 34.1kwh on Jan 20th
Lowest yield - 12.5kwh on Jan 19th

Max load - 24.3kwh on Jan 27th
Lowest load - 9.8kwh on Jan 19th

Max solar yield in 7days - 205kwh between Jan 17th - 23rd

—Undisclosed number of security cameras (24/7)
—Indoor and outdoor lights (17hrs average daily)
—Smart speakers (24/7 standby)
—Laptop charger, phone chargers, smart switches (always plugged, on standby and used on demand)

Average daily energy consumption 20kwh

Something a lot of folks miss when trying to go the renewable energy route is using energy efficient appliances. Converting all appliances to energy efficient ones is as important as getting panels and installing batteries. As you can see, most of my appliances are energy efficient.

Energy management is also an important factor, I make use of smart switches which are automated to turn appliances on and off for different set durations.

My biggest energy consuming appliances for the month of January:

1. Lg 1.5hp inverter air conditioner 184kwh
2. Lg 1hp inverter air conditioner 84kwh
3. Starlink and own router 59kwh
4. Double door fridge 52.3kwh
5. Chest deep freezer 34.63kwh
6. Heat-pump clothes dryer 27kwh

Good morning. I need assistance to connect this as I'm trying to connect it myself.
The circled part, should I cut off the mc4 connectors and join it with the solar cable?
Thank you.

Have you gotten, sincerely need a good shipping service too for Alibaba

AinsSama:
Great inverter choice.

Does your 10 hours of off grid include night time? If yes then your choice of battery capacity (make sure it's Lithium of the LiFePo4 category) will determine how much you'll enjoy it.

dollarnaira:
Only if you can get a durable mc4 bc we have more fake than originals. If at all u got one, a firm connection btw cable and mc4 should not be compromised. There are 6mm and 10mm mc4 choose well.

The other way is crude but works well as the most important is - firm connection and good insulation.

By the way linnov sells graded mc4.
