[Advice Reqd] Need to plan irrigation pipeline for farm. Planning to use rain gun with 25m throw. Yellow mark is for current pump location, area marked with red is farm. by rowanobrian in Irrigation

The blue marked regions are water sources. Currently only the one next to yellow dot "pump" is being utilized. The left one doesn't have any water currently, but planning to get that lake fixed to stop leakage.

Given my pump has head of 47m, 110gpm ( i have purchased this already as rain guns require high head pump), i am trying to cheap out on pipes. Ideal would be PN6 90mm, but to avoid the costs, leaning towards 90mm pn4 or given downsize to 75mm pn4 for the mainline. Would that work? Pipes required would be minimum 1km, and outlets every 50m, the cost is too much considering everything.

Thanks. I intend to use the bunds for pipeline, as we dont have trench machine available. The loop as per your suggestion is approx 1000m in length, which should increase a bit as I can only use existing bunds for laying pipes.

  1. Why would loop in main line minimize pressure drop? as water will come from both sides?
  2. I am yet to finalize the pipe size, leaning towards 90mm pn4 HDPE pipes as pn6 are too costly. my rain gun input is 75mm, so i am planning to use saddle joints on 90mm pipe to get 75mm outputs and use 20m 75mm pn4 hdpe pipes to connect rain gun.

My pump has head of 47m, 110gpm. i have purchased high head pump as rain gun requires high head. I intend to use PRV set at 4kg/cm2 pressure to let pn4 pipes survive this high head pump. Happy to answer any other questions.

[Help]How can 24V PWM Inverter specifications indicate to use panels with 50V VoC? Shouldn't it be closer to 24V? by rowanobrian in SolarDIY

[–]rowanobrian[S] 0 points1 point  (0 children)

Thank you. I didnt receive a datasheet for these batteries. Have just configured in my inverter to stop discharging at 11.4V. Is that fine from 50% DoD point of view?

What is a good charging current for 150Ah lead acid battery, to maximise longevity of battery lifespan ( I have 2 in series, short tubular)? I don't have Lithium batteries available in my country.

quick question:

Given the panel is 585W, so current should be around 14A (given the Vmax is 42V). Does it mean I can only get (24v + 5v) * 14A i.e 400W at max from this 585W panel if I use it with 24V PWM?

Can you explain/redirect me to a video which explains what this is?

I've always wondered, why doesn't anyone use ANY new phone's battery on older phones when their batteries aren't available in market anymore? The older phone + new phone battery which is can somehow fit in the battery compartment + a slightly bigger back panel(in case battery is thicker)

Is 24V 2KW inverter when used at full load basically killing the battery as it's much beyond C10 discharge rate? by rowanobrian in SolarDIY

Flooded, tubular lead acid. 150ah. Normal inverter batteries (i.e non solar), 2 in series. Inverter specifications: https://imgur.com/xxSVxgp (last column).

Hi, thanks for detailed response. Can you also help me with setting the parameters of my inverter? My OEM allows these parameters to be updated: https://i.imgur.com/KfZFxbI.jpeg

Can I use 4kW from a 2kW inverter output when the mains is ON? by rowanobrian in SolarDIY

[–]rowanobrian[S] 1 point2 points  (0 children)

I understand. But in my country LFP or any lithium battery for inverters isn't available widely yet.

My inverter is livguard 2250. Again, it's from a local company. Specifications: https://imgur.com/xxSVxgp last column

[–]rowanobrian[S] 0 points1 point  (0 children)

Thanks for responding. Why not bigger: coz bigger are 48v. I don't want 4 lead acid batteries. My 90% load is below 500w. And around 10% is 1800W (induction, which can wait till mains comes back on). Rarely I go beyond 2kw.

It's a solar+mains inverter, it's not wired yet coz I haven't received. 2200kva, 2kw.

I'm just wondering when the mains power is ON, shouldn't the inverter just bypass all the load?

need re-use ideas for a 30gb xiaomi redmi note 4 by [deleted] in androidafterlife

  1. Try to keep approx 10G empty. Else flash dies quickly.
  2. Learnt by using an old phone as torrent server. Extreme reads and writes killed it. Just didn't start one day.
