Suitable battery for offgrid?

[asdex]

The charging instructions attached must be similar for other batteries people use in solar power system. How do you get on if there are days the array can't produce 40 amps? Say a week of rain when the batteries only charge up on say 10 amps?
Also, I guess the three phases are bulk, absorb, and float?

My PV system is 1920 watt so should charge that capacity depending on sun.

Crown makes good batteries. Would not be my first choice because you can get as good or better quality for same or less money. However if the price is right....

Now one word of warning. Make dam sure you can meet the minimum greater than 40 amp charge current requirement. Recommended charge current is 100 amps. At 24 volts means you need at least 1200 watts.

10 years? Don't count on it. Warranty is only 2 years. To get 10 years is going to require something like Trojan Industrial line or Rolls 5000 series line. Warranty tells you what you need to know. 2 year son Crown, 8 and 10 years for Trojan and Rolls.

Yes these are brand new batteries.

Good deal? these are "brand new" correct?

Thanks, well as long as they compare favorably with the deep cycle Trojan batteries I'll be happy.
Cheers,

All I can tell you is what I read from their spec sheet. How they perform in real life and if they are better than the Trojan brand would be something others may be able to say

I have an option to get these batteries and a good price. Are the suitable compared to other batteries around the price? Crown CR430 6 volt 430 AH deep cycle.
I would get four for my 24 volt system. I would hope to get10 years from them as I normally drag my existing bank which is 330AH down to 92% SOC each 24 hrs.
Given correct maintenance and distilled water when needed.
Thanks,

Well the specs show the "typical" battery life at 20% DOD at 3000 cycles but I would think that is at lab conditions. But if you are only doing an 8% DOD with those 330Ah batteries you may get a long life out of the Crown. Although 10 years may be a stretch unless you follow all of the maintenance procedures perfectly as well as perform an Equalization charge per recommended time frames.
