That what i use na.. 😂 🤣 😂 😂 😁 🤣 🤣 I wanna upgrade soon cause of my pump.. That why i wanna confrim.. Make i leave the 3000w own join the 6000w in a 24v style

dollarnaira:
No tell me say u dey eye "Satchet" inverter oo

Please where did you get the 5KW watched from? Someone on this forum?

Fakeisfake:
Hahaha,

Nice question really but am not sure why the question if you are getting good backup and good use.

I have been using Sachet inverter for close to 4years - 5000W which is 5kw and it's serviced me more than enough at this point without troubling of its self consumption which is tremendously and significantly low with Tubulars until I got 8.3kwh lithium about two months ago and still serving.

Infact, one famous fellow here introduced me to it and he is using precisely same 5000w as we both stress it with microwave, AC, WM, fridge, freezer to it's max with no complain no regrets through and through...

Yes I got it from Nnamdi here on this forum as recommended by my dear good NL TrippleDot now turned friend. Everytime I have the opportunity, I did like to thank these guys real good like demi gods as someone here said I make them feel.. Lol

Meanwhile I found a way to check and the pump is just 1hp which I plan to try out tomorrow Saturday.

If the inverter could do non-inverter AC of 1.5hp and other kitchen appliances, I think this pump would be Bravi too on the moduler inverter.

Please house, I need a fast answer on this. Is wood safe for a 48v 15kwh lithium battery enclosure? I'm planning to use HDF wood. Any one with experience? MrReed, Valto, Dam5reey, Bassdow, Everyone?

Yes it is, hope it is lifep04 and not li-ion

Yes it is. I'm planning to run heater, AC, on it. Is it safe? I'm going the DIY route.

it's a YES and NO kinda answer. I would say NO BUT if the enclosure is spacious enough, and you sure it always would be in airy place, you could go ahead BUT only if you out of options. if you must use wood, kindly also ensure there's enough opening for air flow.

meanWhile, have seen a few with wooden enclosure without issues BUT you never can tell. Myself many years back, have done similar with no issue though not close to the capacity you mentioned.

either way, just ensure you leave enough air vents and the box is wide enough the battery isn't tight in it at all

My battery is in a wooden box. Zero issues. Just make sure the box has holes for ventilation.

Una too get unnecessary fears for here.
Fire fire haba...

As simple as fake dc breaker is, it is old enough to cause fire compared to someone without.

Do we have ventilations in batteries made by professional companies? I need answer here pls.

Check tear down videos of LIFEPO4 packs..

I prefer my cells naked on a hard surface though.

Powerbanks and phones batteries nko?
Vents dey? Am learning too oo

If going DIY, as long as you know what you're doing you have nothing to worry about.

But if you don't know what you're doing, do well to gather enough info from platforms like youtube, tiktok, e.t.c to avoid mistakes.

As for whether wooden boxes are ok, yes they're totally fine and you have nothing to worry about actually. But make sure to pack cells tight and compact as it is what is recommended to reduce early bulging. As for ventilation, leaving holes for vents is subjective as professional packs don't. But make sure to keep your build in a ventilated/aerated space for temperature control.

Hmm just my one kobo.

HDF on its own is a fire Hazard o. This is 15Kwh, God forbid something happens, the wood will fuel the fire. I think steel or aluminum is best. Batteries with this high rating usually comes in enclosed steel but plastic coating in case of an issue. Just a little advice and nothing more.

Wood and aluminium/steel don't have the same thermal conductivity

In terms of gas needing vent not conduction.

This is a 15Kwh
Flame retardant plastics can’t be used for such a battery.

Why not expose it?
Metal or plastic epoxy sheets are needed to lined out the cells.

Bro, I don’t really understand what you mean by exposing your battery bank. I guess you mentioned b4 now that you have used an exposed battery bank for years or so without issues, but it’s still a risk o. Not everyone can be that careful.
Imagine it somehow gets short-circuited or maybe something falls and puncture the battery. Abeg o. Talk more for a 15KWh bank.

My fears exactly. I have finished constructing the HDF box, but I am uneasy. I intend to run water heaters and AC on the thing, and even though I plan to use a BMS, safety is paramount for me.
Do you know anyone here that sells DIY metal boxes?

Lols I can’t market for anyone here 😂, but there are guys here who build such banks.

Anyways, I once asked a DIY guy about such materials, he told me he gets it (quality, properly measured and fabricated ) from China.

FEGEITOK:
My solar system appears to be overgenerating power. I suspect this is due to the DC battery breaker (located between my external charge controller and the main inverter battery bank) being switched OFF. This has happened two days in a row. Note that I also have a separate array connected to the hybrid inverter's internal charge controller.

Key Goal: I need a solution to remotely monitor the system's performance (voltages, current, generation) and, crucially, to have the ability to remotely switch On/Off specific breakers (like the main DC battery breaker).

What hardware/protocol would you recommend for this level of remote control and monitoring?

Once you mention remote monitoring just look into smart breakers, smart shunts and contactors for large current or DC switches.

You can connect these devices to do whatever your heart wishes.

YOu can come DM let's design something that should work for you.

Make sure you size your cables and breakers properly, torque your connections properly too. Not only cells but partial connections and undersized accessories can be a fire hazard.

Good evening house! I’m deciding on a 20kWh lithium battery + 10kVA inverter for my home. I need to pick between Felicity, Cworth, and Growatt — price is NOT a factor.
Please recommend the best based only on:
✅ Durability
✅ Reliability
✅ Performance
Short, clear verdict preferred. Thanks! 🙏

I have used cworth hybrid inverters without much problems. But I won't recommend their batteries.

If money is not a problem, then go for premium brands, like victron and pylontech.

If money is not a problem but you are on a budget, i'ld recommend cworth inverter and 3pcs of 8kwh batteries. Deriy, Mr Reed and possibly Valto comes to mind here.

Really looking for anyone that sells DIY metal boxes for building 48v lithium batteries. Metal fabrication is stressful in Nigeria (many welders are anti-excellence). Jiji and online searches have not provided anything helpful. I'll be happy if anyone can give me a contact

Na gode!

Well the capacity of the Lithium battery in question raises cause for concern. Batteries kinda generate heat during usage and reCharging.
Have built a couple back in the days BUT not close to the capacity He mentioned + on my 3rd build, their was a near ugly experience (battery got so warm) I had to do some searches and saw wood shouldn't be used. I still went ahead sha BUT only gave it enough ventilations on all sides and top + ensured the casing wasn't tight for the entire battery.

Now I also mentioned haveseen a couple professionally done battery banks in wooden casing working perfectly fine BUT that doesn't negate the fact those in the know frown upon it.

Those of us who attend to clients, have bbeen opportuned to move about their homes and in a few cases (more than FEW actually), the location designated for Solar battery and inverter (and charge Controller) ain't often airy enough for something that continuosly works and generates heat along the way.

Personally, if I am doing certain things for myself, and understands the risks, I don't often bother sharing them online so others don't just duplicate such behaviour without understanding the downSides

why not speak with those (e.g Deriy, Mr Reed, Valto) who are professionally in that line of work - they would have learned a thing or two along the way. people like me does such once in a while and it's been very long I last did such.

Also, if the wooden box could be spacious enough to allow enough air flow, then have vents on all sides and also lined with Fire resistant material, and also kept in an airy place, you should be good to go. Sometimes, over careFullNess dey cause slowDown.

Mind you, the battery banks I built, none were close to the capacity you stated + it's been long I last did such.

e go surprise you at certain capacities, even that wood wey dem call non Conductor go begin confuse you. e get reason why you feel different staying close to a high tension line vs a regular line

I know have responded already BUT since you doing it for yourpersonal use, have you thought about using the casing of a desktop computer ?

Imagine, assuming all na unnecessary fears . LIFEPO4 cells are not balloons. I understand the fears and concerns of 15kwh which should be installed in free ventilated closure/room. He is ok with enough epoxy sheets from sides to top. He will be better off with fabricated metal box laced with epoxy sheets. LIFEPO4 hardly get warm to touch.

Your car alone is a big risk, still we all sit on petrol tanks just below us. The list plenty...
