Beautiful, Neat Install.
I love the idea of having that Masonia Board behind, instead of installing directly on the Wall.
welldone.

A few question please:
A) Is that a Combiner Box that the output of the Two Deye Inverters went into (1)?
B) What is that item labeled (2) in the pictured below, where the Battery source goes into, before entering (1) above it?
C) Is it better (or not) to have a Single 12Kva Inverter, compared to two separate ones?
D) How much is each of those Batteries and where is their dealer located?

Thanks

I really want to appreciate everyone on this thread for the knowledge and enlightenment you share.
I started my solar journey before I knew this thread, and I fell heavily into the hands of a predatory installer. Thank God for this thread and its good people, things are now very much better.



@JoeSef0, thanks for introducing me to the thread.

Thanks to @Dam5reey. I bought the protection box set and inverter from him. He also took the inverter to the service center for repairs and it was repaired under warranty. (About 1 month after purchase, lightning struck and destroyed 90+% of solar installations in our area)

Thank you everyone🙏

I asked few questions now but he’s just a seller, he doesn’t know it all. I just wanted different opinions and learn from the experience of others since a lot of people here have been in this solar journey for a long time.

HeavenlyBang:
This their DOD talk dey always vex me
Wetin concern capacity with DOD

To be fair I've recommended their 12v 1.5kw inverter to multiple people who are using them without issues so far. No idea why they keep overrating their batteries, considering the prices are good at the actual capacity.

Unfaized:
Regardless of how good an offer is, false advertising is a crime.

HeavenlyBang:
Embarrassing. How are they getting away with this?

Are you planning a teardown or capacity test.

Would be interested if you plan selling off afterwards

INSPECTORMAX:
Battery Procurement Dispute – Request for Fair Resolution

I’m sharing this to seek objective input and a fair resolution regarding a recent solar installation carried out by Trippledots.

From the outset, my clear preference was LVTOPSUN, based on its features, reviews I got here on NL and other platforms, warranty, and support structure. To confirm pricing, I independently contacted Solaris Surge, who quoted ₦1.9m. I communicated this to Tripplredot and stated I was willing to pay ₦2m to cover procurement and logistics.

At no point did I request a locally made battery. The decision to move away from LVTOPSUN was based on Trippledots recommendation, where I was advised that LVTOPSUN would not provide a full 15kWh usable capacity, while a locally made alternative would provide a full 15kWh and comparable overall value. Based on this professional recommendation, I agreed to the change.

Before payment, I had also informed my Quantity Surveyor (QS) that I was proceeding with LVTOPSUN at ₦2m, which he confirmed was fair. The locally made option was not discussed with my QS at that time. It was only after the battery was delivered that I shared the details with my QS, who highlighted material differences in value, pricing, and functionality compared to LVTOPSUN.

Following further independent research, I confirmed that the installed locally made battery (Mr Reed) is commonly sold around ₦1.6m and has more limited functionality compared to higher-tier options. I also found that alternatives such as VALTO, sold around ₦2m, offer better communication features and overall functionality at a similar price point.

After installation, additional differences became apparent, including shorter warranty coverage, lack of a Lagos service centre, and missing communication features, some of which required additional cost and I was charged separately for and are still not functioning at the time of writing.

I attempted to resolve this privately by requesting either a reasonable price adjustment or a return to my original LVTOPSUN preference. After reasonable follow-up, I have not received a response.

I’m open to constructive opinions on what would be considered a fair and professional resolution in this situation, particularly where a client’s original product preference was changed based on professional recommendation without full disclosure of material differences.

Hello bro. I use a LVTOPSUN 5KWH BATTERY, 5KVA GROWATT SPF 5000 ES INVERTER.

I want to ask if this is normal. During the afternoon when the sun is shining, I expect the battery to go completely into idle mode once it gets to 100% but no o; the battery starts discharging by 0.33A.

Regardless of whatever load I put on the inverter, the battery discharge current remains at that 0.30 - 0.33A.

Usually by evening around that 6pm/7pm the battery would have discharged to around 95-96%.

Is this normal, I feel the 100% should just stay (remain idle) there till I start using it around that 6/7pm.

I have experienced such before but it's been very very long. First check your charge controller (if not using Hybrid inverter) else check to ensure the Charging system is not cutting off due to capacity.
To best of my knowledge, such only happens when the Sun comes out very very well (when the charger's output is high enough).

Hopefully, the charging system is configurable
