Step up to 48v dc, and the current is halfed... 34A dc.
On a 600Ah battery bank, that draw is negligible

Oga Pranil ... making sense since 1914

Haba shey that your AC na old model 2hp wall unit brand ? My AC dosnt take up that amps but I always emphasize more on Oversizing PV array & a well sized battery bank to AC users especially those who run theirs at night .. Cheer's !

Second reason might be typical network issues..
Either way I needed a ensure the network is restarted once it has died.. took me a while to fix this but I think I have found a fix.
setup a daemon service which monitors the network process file and pings my server. if after 300 seconds it can't ping or the network process has stopped, it initiates a restart. I implemented new process watch this morning so let us see if it works.

@bigbrovar,

Had the same issue with my raspberry pi uploading to emoncms website too. At first, it was difficult tracing why it happens but i was able to pinpoint it to services stopping abruptly. I noticed as soon as you do a reboot, it starts uploading again. So what I did was to setup an autoreboot in crontab to automatically reboot the Raspberry Pi at at least 5 times daily and this solved the problem. I have since reduce the reboot time to once a day (12pm daily) and have not experienced any downtime since.

Power your fridge, freezer, AC with solar during the day and public power at night when available. Don't kill your batteries with huge load. Price is 16k for 63a

I'm going the route of DIY powerwall, and thus far I'm pretty impressive with the result.
It's a 7s100p setup of 190ah. I intend to crank it up to maybe 7s 300p/400p.

I need a 100/125 amp 3 phase ( TPN) mounted in the outdoor box if available for my office - pls. email me quote anil_ghatikar (at)yahoo.com

JUO:
good move how do you intend to constructthe bms? I want carry out on this also

I planning on manually balancing them once in a month.

llooking for a similar solution for my cctv internet, i intend to power the internet with a glo 4g sim in a mobile phone-hotspot, but hv experienced this sudden outage that requires a phone reboot to resolve and restore network. the rebooting and restoring hotsopt isnt possible on most phones/apps, what do you reommend i use? how easy is this raspberry pi?, i gat 3/10 IT programming skillz , DO U THINK i can handle it?

The lowest cells are 1500mah and the highest cell is 2500+mah.

I used repackr.com to group the cell

I think it is not advisable to use a mobile phone for hotspot since the use will require the phone to be perpetually ON for a very long time. Also, the phone can also get hot with time. And schedule reboot in mobile phone is not that common unless you get a third party app.

Why not get a mini, micro-router or pebble. With that, you can then connect your cctv camera with wifi or network cable. A raspberry pi is just mini pc so that may not work for you. In addition, other forum members can also share the experience if they feel it will work.

Good evening house, please I need to fix a 5kva cyberpower inverter. If anyone has idea or person that can do it, please get in touch with me.

earthrealm:


challenge is..the cctv only has lan input, a modem with sim input and lan output would be my best option, but am yet to see that, so intend to do cellphone hotspot to modem with lan output

Good people, can somebody please advise or say something. I know I am not pranil or Niyi.

DMerciful:
Get inexpensive BMS from aliexpress even the ones with Bluetooth such that you can monitor system performance up-to individual strings on your android phone

NiyiOmoIyunade:
Ah Oga! Nor be so o. I do not have a solution to this problem so I kept quiet waiting for someone who can help to talk.

The thing is as far as I know that CyberPower is a very very old system and Prag discontinued support for it long ago. Few if anyone would have boards or spares for it now.

Perhaps KieKie on this forum would have or know someone who can help you fix it. He still has an ancient cyberpower 3.5kva he uses to carry his heavy loads

If you are unable to fix it it or the cost of fixing is prohibitive then it might be time to get a more modern replacement.
