uche393: good evening all, i have seen some people complain that inverters makes powerbanks to swell how true is this claim? i was telling a guy who runs a charging center about installing solar in his shop and he pointed this claim too, he showed me some customers who had swollen powerbank as a result of charging with solar.
I’ve been using an inverter to charge my power bank for many years. None of my power banks have swollen so far.
Swollen power banks are more related to the quality of the battery used to make the power bank or to charging the power bank with an inappropriate charger. A good power bank with a reliable Battery Management System (BMS) should still prevent damage from occurring.
SourYoghurt: please guy, what's your experience with Thermocool Inverter Freezers, Does it freeze and ice liquid like conventional freezers when used with solar.
My current freezer, barely freezer things probably because it's older.
Please, I need your guidance.
Buy Scanfrost. I'm biased, I use a Scanfrost. Everyday I fight to break stock and other foodstuff stored inside there. This night I had to put the chicken there in airfryer to be able to cut it.
Got so frustrated with breaking up food, which are frozen, that I ordered an ice pick to help me break up blocks.
Disclaimer: I use a servo AVR. Freezer plus every devices at the house, never sees less than 220V, on NEPA or on inverter. Dunno if that counts.
Please who knows where I can get this charging module?
Or something similar capable of charging heavy power banks.
Want to buy a few and connect to my DC converter
Thanks

I bought something similar, for $2.20, in AliExpress. Mine just have only one type C output. Input voltage 10v to 30v. This charges my phone pretty rapidly. Totally works.
chris81964: LIGHTNING STRIKES... BUT MY INVERTER STOOD ITS GROUND! 🔥⚡
Do you remember that video I posted about how lightning can shut down even the best inverters? Well, let me take you behind the scenes of what just happened — and trust me, this was not your average rainstorm.
It started with a LinkedIn post I read some time ago — multiple inverters within a 5 km radius had failed after a ferocious lightning storm. These were properly installed systems, with earthing and SPDs in place — yet they still failed. That got me thinking. That got me experimenting. That got me ready.
Then yesterday happened.
The heavens opened. The sky lit up like a thousand fireworks. This wasn’t just lightning — this was lightning on steroids. Strike after strike. Some so violent they triggered car alarms in the neighborhood. The whole area was under siege from Mother Nature herself.
And there I was… watching… waiting… monitoring my system.
GUESS WHAT?
Not a blink. Not a flicker. The lights held steady. My inverter stood its ground like a warrior. My solution worked. The theory became fact — and it survived a full-scale attack.
Whew. That was intense.
👉 Watch the full video to see how I solved a problem that takes down systems worth millions. If you care about your investment, you NEED to see this.
1. I don't know if there is expertise about installing it without feeding back into the grid. 2. It probably won't work. 3. If it works and feed back into the grid, you may be supplying electricity to the whole town or worse get someone electrocuted down the line. 4. 3 may not happen because grid tie inverters work with grid, once the grid is down, they also go down.
Finally, it is a very bad idea. Don't do it.
GRID tie does not necessarily have to feedback to the grid. I've seen a couple of grid tie work very well in Nigeria in a niche area that only requires power during the day (banks, schools, etc).
Pabodo: Good afternoon, Please can one use a Grid-tie Inverter with battery? If Yes, how can it be done and any advice to go for it or not I want to buy one and send to Nigeria, most I see are grid-tie (Sunny Boy SMA) Thank you guys for the good works you are all doing
Like he mentioned, running it in Nigeria for home wouldn't be great as it requires a constant grid supply (NEPA/ generator) to work. Nigeria don't have that supply in much quantities.
So you are better off buying SMA, but instead of the grid tie type, buy the hybrid type that requires battery as it's best for use in Nigeria.
I know you must've seen a lot of grid tie outside Nigeria, people often get it to reduce their utility bill. Not something you'd bring into a country with epileptic power supply.
A lil note, if buying from North America, just ensure output voltage is 230v 50Hz and not 120V 60Hz.
AndroBlaze: Could we be in the last days of lithium? Heavier but possibly cheaper batteries have started their march in the battery capital of the world.
ask4bk: Now permit me to sincerely seek your advice. Would you advice me to constantly run my deep freezer, refrigerator, occasional washing machine and blender on the 6kw Growatt inverter (from fouani) in a dusty environment of far northern Nigeria with constant 40ºc temperature?
If you think it's OK, I'll get it. If not, give me a better alternative.
Every once in a while use a dust blower to get dust off of it.
This is applicable to any inverter you buy as too much dust on electronic components leads to excessive heat and eventual thermal runaway.
Rumplesteelskin: Did a drain test, still stuck at 26.8-27.2 V after hours of charging. Did the final test today, disconnected the inverter from the battery, and the inverter went straight to 29.1 V, while the charge controller that is connected to the battery shows 26.8 V. So, I have ruled out the inverter limiting the charge current
The deyri has jk bms, and the cworth has a different bms. So the first RPi with solar assistant is communicating with the JKbms of the deriy, the inverter and the victron smart shunt.
The second Orange Pi running SA is communicating with the cworth battery via CAN2.0, I couldn’t get cworth to communicate via rs485, it seems they use different communication protocols via rs485, but the CAN uses standard protocol.
Dabss: go with mono facial. The bi-facial is only 615w when mounted correctly where it can get the reflected sunlight rays. If you mount on the roof you won’t get 615W. Just go with mono facial either ways.
That's not really accurate . You get more than 615w if mounted on the ground in a way sun gets to the underside. You could get up to 720w or more from this 615w PV when ground mounted and appropriate conditions met.

Why do you have two raspberry pi running solar assistant?
dunmorrix: They too, they use third party shipping company just like the way importers do and now the item is no where to be found.
The third party shipping company is asking for container number and tagging lists.
They told me to cancel the dispute, yet third party shipping company can't find my package, while the third party shipping company in china is saying the package is in there Lagos warehouse.
omotoda: This is a terrible design. Someone should advise them to improve on this.I remember those days , I use my PWM charge controllers to monitor battery voltage without connecting to PV
dunmorrix: Please should I apply for refunds this is going to 97 days and them say Na sea shipping. I placed the order since February 2nd of this year.
Next time buy in Alibaba and use a third party shippers
Machiny: Was a faouni today and it's just 615w panel they have. Both BI facial and MONO facial are same price. Which is preferable? Also a transformer base and non transformer base hybrid which is better?
Obnoxious2001: Is not as if they don't know, is just that they will still do something shabby and call it protection, so they end up pocketing the money....
SolomonGrundy: Good morning my people, it seems lightning has damaged my DC breaker, I woke up this morning to notice that my battery is not being charged by the panels, so I decided to put off the DC breaker switch and then put it back on. Noticed there was a bit of spark.
As it sparked, I saw the input wattage from solar panel go up a bit. After the spark the wattage disappeared. Attached is the DC breaker switch. Would I have to replace the breaker switch? I'm thinking of unscrewing the spd box to ascertain the level of damage.
Can I safely power a 12V CCTV camera directly from a 12V battery (charged by solar)?
I have a CCTV camera that normally runs on an adapter rated for 12V DC, 2A (input: 100–240V AC). I want to bypass the adapter and power the camera directly from a 12V battery (such as a sealed lead-acid or LiFePO4), which is charged by a solar system[b].
[b]My questions:
1. Is it safe to connect the battery directly to the camera’s power input? 2. When fully charged, the battery can output around 12.6V to 13V—is this safe for the camera? 3. During solar charging, voltage can reach up to 14.5V—would this damage the camera if it's connected? 4. How do I ensure correct polarity when wiring? 5. Is it safe to charge the battery and power the camera at the same time?
Any advice, experience, or wiring tips would be really appreciated!

Try a DC to DC converter to ensure safe stable voltage.
mdpeace: Hello everyone, please how much will it cost to send a used laptop from Germany to me here in Nigeria and which shipping company would you advise me to use
Whatever you do, don't use DHL, FEDEX or UPS. If you do, you stand a very high chance of paying crazy high import duty.
bassdow: MorningStar and Deye actually are on the expensive side for a lot of us. Something like epEver is much cheaper and has high quality. Mind you, cost of a small used ePever charge Controller is a lot higher than a brand new high amperage and voltage charge controller from all the funny names out there.
Epever inverters ain't cheap o. In fact in China the price difference between Deye 5kw and Epever 5kw is less than $120
bassdow: Even when well mounted, don't think the GAINs is worth the extra price
Most bifacial sold is the same price or cheaper than conventional PV. I haven't seen any with prices higher than conventional PV, yet, of the same capacity.
