Please house I'm looking for a reliable Hybrid inverter 7.5kva 48v with at least 60amps Mppt.

The reason I'm going for hybrid is for ease of future expansion. I currently have a Victron Energy SCC 250/100 but just incase I need to do minimal expansion in future I may use the hybrid section of the inverter.

Someone suggested voltron brand 7.5kva, 48v with a 60a mppt charger but I just want to make sure it's a good brand.

Who cares

Joy solar panels.
They come with short cables (less than 900mm or 3ft) which makes it difficult to connect is series vertically.

Out of 12 panels I bought I had to open 2 of the panel control at the back to solder one of the terminals.

Buy at ur own discretion

Shots fired

The most difficult part of the work has been done which is earthworks and concrete works.
Laying of track is a very simple work

impressive congrats. you no wan carry last for solar panel academy. see panels. my question you upgraded batteries from 48v 200 ah to 48v 600ah and added more panels and charge controller.
what about your inverter is it the same charging your new battery bank or you upgraded or added external charging.

Yes same Must Power 5kva.
Rugged piece of equipment, neva found wanting for any reason.

My load has remained constant coz my house is wired with 2 separate Distribution Boards: TP&N for heavy loads; SPN for lights, Tv and specific sockets.
So my load has been constant.

What a beautiful setup and a wonderful journey so far, it is not easy o.
From the 4pix u uploaded, I could only see that ur batteries enter absorption stage 1 out of 4 times, no float at all. is this a regular thing?
If yes, then u do not need any more panels, the ones u ve is okay. What you need now is ENERGY CONSERVATION not generation. Bigrov, where are you?

Yes i have increased capacity from 4.5kw to 6kw by next week i will add the final panels which will bring it to 6.75kw.

But i'm not bothered about the absorption stage coz from Monday morning to Friday evening we usually have 100% lite from PHED so the batteries remain in float mode.
Basically the solar system works starts working from Friday evenings.

congratulations on the bold step bro. however, after soaking the garri, you still made a mistake. Dmerciful just pointed it out

NEVER mix batteries of different brands; even if they are same capacity and technology. even if they were manufactured the same day and time. They can never ever have exact same characteristics.

few manufacturers do state it in the leaflet that comes with their batteries. Mpower just re-branded their battery. The new ones now comes with a leaflet with battery do's and don'ts. one of the do's is "always use batteries from same manufacturer within a bank of multiple batteries"

it would've even been a little bit manageable if it were maybe, 8 from one brand and 4 from another brand.
nevertheless, mixing batteries from different manufacturers, is just a NO NO

It wasn't originally my intention to mix the batteries but i changed my my mind on the Nexus batteries after buying 6. A friend told me of the nasty experience he had with them.

The Bluegate batteries are sold with Warranty and i have used that brand for close to 10 years.

My worries are coming to pass as i have noticed 1 of the Nexus batteries is behaving funny

Yesterday morning and this morning it was reading 12.4v while the rest are 12.6v.

When it starts charging it will be reading 14.8v while the remaining 11 batteries are reading 14.3 - 14.4v.

Basically that particular battery charges faster and discharges faster.

I don't know if its the HA02 equalizer as someone suggested cos these batteries are just 2 weeks old.

DMerciful:
If one could,better to buy same brand, same batch cos they do have different internal resistance no matter how little

If only u knew the nr of days I soaked Garri to be able to afford 12 batteries (N1.3m) within 6 weeks.

DMerciful:
Regarding harvest, several factors affect yield.
1) The position of the sun in the horizon. The sun moves from tropics of cancer to tropics of Capricorn and since your panel is fixed at a particular angle, harvest will be affected esp if you panels are not facing the optimum angle of 6degree south.
2) During raining season, though cloud cover is more however the atmosphere is clearer from dust particles that affects the amount of light incidenting on the panels. So instantaneous harvest may be higher but average daily harvest may be lower than dry season. The panel's also runs cooler during raining season and cooler panels harvest more
3) The state of your batteries(SOC) at dawn also determines harvest. There is a possibility of consuming more during dry season from dusk till dawn due to running AC to overcome heat and as such creating room for more harvest.

I see that you still mix different brands even after the initial battery failures due to batteries of different ages..Kindly clarify

They are all new batteries.
Just that 6 are Nexus while 6 are Bluegate
All are SMF VRLA batteries and they charging profile is almost similar Absorb 14.7v; float 13.7v

(I basically choose the midpoint in the range of the batteries)

Observation Nr 1:
Avoid the temptation of mixing old and new batteries u will eventually regret it.

Observation Nr 2:
Try as much as possible to have a battery voltage indicator connected to all the batteries so u can always see the voltage of each battery and know when one is under performing so as not to drag the entire bank along with it.

Observation Nr 3:
I am still wondering if one can truly sustain on solar. (My saving grace is that when PHED lite is on it can stay as much as 2 weeks without blinking but when it goes off it takes another 1 week for it to be restored.)

In Port Harcourt during the raining season harvest was very very low. My 4.5kw solar array usually puts out about 5kwh – 8kwh on good days and as low as 3kwh on bad days.

Initially I tot there was something wrong with my connections but on some VERY rare occasions when the sun shines all day it puts out about 14.5-15kwh with instantaneous power at average 3.4KWp - 4.1KWp.

Since the coming of dry season here in PH, my KWp has reduced to Max 2.6KWp for a 4.5kw solar array but the daily harvest moved up to about 14.5+kwh.

I am a little confused coz I was hoping that my KWp will remain high now that the sun is here

Pic 1 & 2: are from today and yesterday

While

Pix 3 & 4: are from early November during tbe raining season.

Is it safe to assume that Kwp is better during the racing season than during the dry season?

Obi should be crowned liar of the year

My solar journey so far.
( All connections were done by my humble self with good amount of knowledge gotten from this forum. )

Earlier this year I decided to add solar component to my inverter of 4 x 200A battery (48v 200A – 9600W).
So I connected 12 units of 250w solar panel (3kw) with 80a Flex Max Outback CC.
I later increased my battery Bank from 4 x 200A
To 8 x 200A bank (48v 400A) in April this year.

Mistake Nr 1:
When I was still using 4 batteries I noticed 1 of the batteries reading below 11v, so I changed that single battery and added the new battery into the bank. (March this year)

Mistake Nr 2:
I bought 4 extra batteries in April to increase the capacity, thereby mixing 4 + 1 = 5 new batteries with 3 old batteries Totaling 8 batteries.

I later increased the Solar component to 18 units of 250w panels (4.5kw) thereby maxing out the CC capacity of 4kw for 48v setup.

In November this year I noticed that the batteries drained to quickly, although the inverter had neva beeped, I decided to check the batteries in the morning and noticed the older batteries were around 10.8v – 11.2v.

Having learnt my lesson I quietly bought 12 new SMF batteries (6 Genus 6 Bluegate batteries) this December (48 x 600A), I also decided to buy battery indicators to know the voltages of the batteries at all times.

I have also increased my solar component to 24nr 250w solar (6kw)
18nr 250w panels (4.5kw) are connected to one Flexmax 80A Outback CC, the other 6nr 250w connected to the second Flexmax 80A Outback CC.

So basically I have a 6kw Solar panel array with 48v 600A battery bank; 2nr Flexmax 80A CC; 3nr 48v battery equalizer; 12nr battery indicators; 5kva Must Power Inverter.

Observations coming in the next post…

Namzy:
Looks like voltronic axpert 5kva aka ipowerplus 5kva. I know must inverters have an axpert clone with mppt and another with pwm cc

A friend sent this to me
Said its the same as MUST

It seems that it's same company that produces all of them.

Pls where can I get a 5kva hybrid MUST inverter.
I heard they are a different brand from Must power inverter.
Thank you

With clowns like DINOsour Melaya in the Senate why wouldn't their bills be full of errors.

All the bills which the President withheld his assent he stated the reasons clearly and I haven't heard the National Assembly overriding his veto.

That is the beauty of having a Constitutional Lawyer as a VP.

All the lawmakers know is collecting bribes from lobists and producing junk bills like they did with that paramilitary outfit (can't remember the name) which would serve no purpose

Lies

These are contract staff naa..
They can be disengaged with only a month's notice.

The same thing happened in amnesty but some are back in their office
