i looked it up and apperantly daisy chaining UPS's is bad mojo..

For the cheap ones, yes.

 

For the cheap ones, yes.

well intex isnt exactly high end.. i only picked that a few months back because i once saw it in what used to be a large computer store in Montreal called future shop but i think bestbuy bought them or they just shut down due to online competition

 

2 days with 2 ups's daisy chained, so far, no smoke and no bad voodoo... im thinking i should add a wire from each grounding prong to the metallic earthquake beam in my home.. at this moment i only have pc ground pin to wire to scratched portion of that beam... i know its excessive.. but id rather feel safe than sorry.. i feel confident each time i touch the metal frame of my pc and feel nothing.. no buzzing nada....

 

well from 0600 one of the daisy chained ups's was chirping so i put the main cyberpower ups back on city power and it stopped chirping

tried again around noon thinking the cheap intex wasnt functioning correctly but zero change.. i think it is because my beast ups cyberpower doesnt want to be fed anything modified... OR because i took my chances and put pc to sleep instead of shutting it off... yes it might seem strange to some of you to tuck your pc into bed (yes i am kidding) but ever since the age of 12 ive had a 486 (before pentium) it has been a non stop obsession with me... no i mean i just put linux into suspend mode which reduces pc consumption to a bare minimum..... in the windows family yes i believe that is called "sleep mode"

The cyberpower UPS is wisely saying modified sine power is crap. I hope the AVR function is still working correctly after trying to correct the square'd waveform for a few days.

i really dont mean to sound rude but i have trouble understanding most of what you say, im sorry, no i am not a linux nut... im just forbidden from using microsoft as an OS because of its security flaws, if i failed to mention it, ive been in service to the Canadian Armed Forces since 03.... and im sorry but windows. amazing OS simply does not offer security as macOS or linux or freebsd... altough for video games, yes, windows is top notch... as for AVR.. i dont have that wave meter.. or osciloscope to see what is the output in the output in the back of the UPS but no chirping at 0600.. so yay in my later years ive found that waking up at exactly 1206 in the afternoon gave me perfect rest and if you dont mind please explain the USB portion of your statement, i can connect the ups via the printer/usb cable that came with my ups ???

if ever im more comfortable financially, should i aget another ups.. identical to what ive got now ? cyberpower PFC puresine ? it will be dirty wall power to 1 cyberpower ups and then from that to another cyberpower ups..... and should i ever go fully off grid.. and rely only on battery power .. should my dc to AC inverter be puresine output as well ??? but this will be years into the future.. maybe 5 years or so

 

sorry, i mean to say in 5 years ill be entirely living strictly on solar panels.... i figure i need 3000 watts available to me at all times.. so i need 10 solar panels of 320 watts.. and about... at least 22 more 12v 50ah batteries.. by then i imagine my dc to ac inverter will be at least able to put out 3000- to 4000 watts of pure sinewave.. maybe THEN ill add another ups identical to this one... it does have like 9 or 10 outlet in the back.. its kinda like a powerbar with a battery.. which is actually brilliant... , please feel free to point out any flaws in this beautiful vision in my little pepper mind sorry im from Quebec, ive been accustomed to none polluting power my entire life if you are familiar with HydroQuebec, yes i believe there is 1 nuclear power plant somewhere.. but i believe the uranium rods in Toronto get recycled or re-radiated somehow in a nordic country, Finland, Denmark or Norway, those guys are living in the year 3000 oh sorry im drifting off topic, i said that because Philippines is heavily reliant on Coal and heavy oil to produce power although i do believe i live 2 to 3 hours away from the 2nd largest geothermal power plant on earth.. 1st being in NZ.. 2nd in ormoc city, leyte island, Philippines, sorry, nevermind.. i just checked on google.. it seems my neighbour was overstating things.. the 2 largest geothermal plants is either north of san fransisco.. a collection of 22 power plants..poducing 900 megawatts or China.. producing 6.... gigawatts.. cmon usa ... wow things seem alot different when im on THIS side of the world... although, hoover dam is pretty cool

For a 3 or 4 kW system, you will need to increase the battery bank voltage and invertersworking voltage to at least 24vdc, with 48vdc being better to keep wiring and components sizing practical. The solar panel input strings (with a total power of twice the expected loading so you can charge batteries and use power) should be at least 120VDC to a good MPPT solar controller like the FM80.

panels.... i figure i need 3000 watts available to me at all times.. so i need 10 solar panels of 320 watts..

Only if you get full sun 24 hours a day!

of course, that i am aware of.. all 10 solar panrls parallel connected parallel (as in all the positives of all solar panels into 1 cable and all the negatives going into 1 cable going down to my apt on ground floor... 20 mgoing into a better mppt or pwm.... i believe what i have now is a BS mppt.. it has a usb plug in it.... but it DOES take the 18-21 volts that my current panels are providing and converts it into 12 or 13v that my 2 batteres happily accept

may i ask if a 24v system is the best ??? the only heavy pulling on the batteries will be the condensor/evaporator of my AC unit.... which unless im wrong usually pulls 1000 watts.. please correct me here.. if my current window AC sais hourly wattage is 550.. means it pulls like 1000 watts or so for evaporating the CFC.. and the remainder.. its just a electric fan inside Spinnig, which i believe only takes 50 watts.. so all that in the span of 1 hour.. totals 550 watts... this of course i kinda put together in my little mind, so please correct me.. i understand that 24v system will put out bigger loads.. but other than the AC.. a petite fridge, slightly smaller than an office fridge and my gaming laptop... wifi modem.. a few electric fans to keep the air in my home circulating... someetimes i use a small projector for enertainment, otherwise, i have no issues gaming on a good pc 16 hours a day.

oh.. a hot water kettle for making coffee

touché,,and i am aware of this, however my emails to evil villains about slowing earths rotation have never been answered, but i wont give up... so my only solution is to use 10 panels receive 3000 watts (i know that isnt realistic) but im not gonna be consuming every single watt... some of it will sink into the batteries... for overnight use.. OR.. ill have a little wind turbine thingy.. i think some people call it a wind generator, however it doesnt actually generate wind.. it isnt 1950 anymore, humanity has other options than to ram a plug into a wall.. so that is my mindframe..

 

so all these batteries... linked together in parallel (keeping it simple for now) should go to my electronics via a dc to ac pure sine wave inverter or ANY inverter will sufice ??? although my cyberpower appears to dislike modified sinewave

Because 12VDC systems are inefficient and have high parasitic (wiring) losses even at the 1000W level. In low voltage power engineering, current is not your friend. Higher currents means more valuable electrical energy (as fields surrounding the wires and conductors) is being converted into heat as the Kinetic Energy of the charge carriers increases unless you use larger wires and conductors to decrease the current borne "vibration energy" KE thermal losses.

The quality level of the available equipment also takes a big jump at 24VDC and higher. Most of the 12V stuff (cheaper, less robust designs) is designed for RV type mobile operations, not 7/24 duty cycles.

i see.. so.. 24v.. i can do that i THINK 2 batteries have to go pos to neg... and the rest in paralelle ? pos to pos and neg to neg ?? so id have to change the mppt or pwm.. the inverter
but 1 tiny question... volts 12 times 50 ah.. so 1 battery is 600 watts.. and 2 in parallel it becomes 1200 watts
if i intend to have 10 batteries.. if i link every battery in series the voltage keeps doubling...

im sorry i that messages makes no sense

Having a large number of batteries in any string configuration can be problematic without active BMS management.
If you're serious, buy the largest Ah capacity battery practical and move away from dumb Lead-Acid to the much better modern chemistry types.

i completely agree with you, however ive seen too many chinese lifepo4 batteries catch fire on youtube videos.. and there is no percaution i can take to ensure my safety.. im also aware of the need for a bms... so forgive me for being a big dummy and sticking with something that will not explode.. SLA i already have 2.. why not continue in that same build ??? yes it will take more space but... i fully intend to expand from my 50 sqm 1 room apt into something more spacious

 

however ive seen too many chinese lifepo4 batteries catch fire on youtube videos

Are you sure? LiFePo4 are supposedly not dangerous like other Li Ion chemistries.

yup.. when the Chinese hover boards came to Canada over a decade ago, they were catching fire left right and center. cant imagine the states got any better quality than we did....

and there is enough videos on youtube of people using those chinese lifeo4 batteries in their solar power setup and poof.. fire..... i dont have any fire trauma in my life and i certainly dont need any
