Hey folks,

Just wanted to drop a solid recommendation for anyone considering the new Deye 6kW hybrid inverter. I recently got my hands on one and have been running it pretty hard to see what it’s made of — and honestly, I’m impressed.

First off, it’s parallel capable up to 16 units, so scaling up is no issue. Efficiency-wise, this thing is tight — I clocked idle power draw at just 30W when running a 1.6kWh load, and it only pulled under 100W even with 4kWh flowing. I also put max sustained load of 6kw, it took it like a champ! That’s some seriously optimized idle-to-load performance.

Now, let’s talk MPPTs. The Deye has a new feature under Advanced Settings called “MPPT Multi-Point”. Game changer. One of my PV strings gets shaded after 1PM, and normally performance drops off hard. But with this setting enabled, the inverter kept pulling full amps from the unshaded panels — like it knew exactly what to do. I ran the numbers — the gain was legit.

Sound-wise, it’s practically silent. It uses just one fan, which only kicks in at high loads. No annoying coil whine either — just a soft whoosh when it ramps up. I’m running 10,280W of solar into it, though it can handle up to 12,000W on dual MPPTs. It charges and discharges at 135A, and with an IP65 rating, it’s perfect for our dusty, humid conditions. Built-in WiFi made setup easy and remote monitoring is clean.

Small Catch:

Since it’s a newer model, Solar Assistant doesn’t support it yet, but I checked — it logs every 60 seconds and pushes data every 5 minutes to the Deye app/web. Accuracy is within 98% of Solar Assistant’s metrics, which is impressive for a stock system.

I also tested it with both closed-loop (BMS comms) and open-loop (voltage-based) battery setups. It handled both without breaking a sweat.

Cost & Efficiency:

It set me back ₦950,000, and honestly? The performance outshines Growatt, Axpert, Sumry, Welion, SMS, Sako — pretty much every other popular Chinese inverter I’ve tested.

One thing I’ve noticed with a lot of these cheaper all-in-one units is they use low-quality conversion components. For example, an SMS inverter I tested lost a constant 4.5kWh/day due to inefficiency. Doesn’t matter if you’re generating 9kWh or 30kWh — you’re losing a minimum of 4.5kWh daily. That’s 135kWh a month gone. Discharge efficiency was also poor — I was only getting 86–89% usable energy out of a 10kWh battery.

With the Deye? I’m seeing up to 96% usable, meaning 9.6kWh out of a 10kWh pack. That’s a huge difference.

Testing Other Brands:

I also tested the true output of other inverters, and most are overrated. A “6.2kW” Sumry unit (sms, welion, sako, powrmr, anern, victor max, daxtraumn etc) barely managed 5.6kW sustained, and a “10.2kW” SMS one capped out at 8.2kW. Turns out, they rate them based on PV input, not actual AC output — which explains a lot.

My Brand Ranking (So Far):
• #1: Deye – most efficient and best built
• #2: SRNE – decent performance, but not quite Deye
• #3: Growatt – solid, but a step below SRNE
• Way down the list: Felicity Solar and similar budget brands

That said, I do have beef with SRNE’s pricing. They’re trying to pass off their gear as premium because they’re UL-listed and in the U.S. market. But their 16kWh battery is way overpriced for what you get. It’s just REPT cells rated at 8000 cycles (anyone can get their hands on this cells, and no guarantee its actually grade A sef), and nothing special inside — no thermal padding, no fire suppression, no fancy BMS features. You can get better-built packs from Deriy, Bicodi, Gospower, Lvtopsun, or Valtech for less.

Quite a long read, if you have any questions you can ask me.

How would u rate the sumry units in order of performance?

I am waiting for Dami to buy one for science 😁

Drgreatone:

You the second person mentioning this battery brand, how well do they perform?

It's in the market and some sellers list it here too. DYOR before picking a brand

cutefy:



Okay thanks for ur response.
How can I upgrade to 80A. The only size I see around here is 60A..

Good evening people, In my quest of finding panels that generate 100% of their rated power, I found that mono perc panels does this well. There isn't enough data/video of topcon panels to indicate they do this too even though topcon is stated to have more efficiency than mono perc.
So, please, if you have any panel like jinko that uses topcon technology, kindly state the highest wattage you've gotten from them.

Bro I am a newbie to all these stuff and I want to purchase a solid bybrid inverter or solar gen system. My apartment total load is between 1Kw to 1.6Kw. I am looking at a budget of 2.5m. Please advise. So many information out here. Gets pretty confusing deciding on what to settle for. Need your guidance please on a solid system to settle for. Thanks in advance

You can do pretty much with this budget

Definitely yes!

Perc is a new solar panel technology.

People believe that perc solar panels, charges at night (not totally true) but then, it has good efficiency in trapping energy even in poor climate

your total load is different from consumption.
Consumption is what you need to size.

2.5M will get you 6kva Inverter and 10/15kwh battery... Buy use understand your consumption and size for the panels to take you partly or off Grid.

I have done the total consumption estimate calculation. Please see below. And the 2.5m covers panels (4 x Jinko 550w and above minimum), accessories and installation fee.

Device Quantity Power (Watt) per unit Total Power (Watts)

52" LG Flat TV 1 ~120 W 120 W
Laptop 2 ~60 W 120 W
PS5 Pro 1 ~220 W 220 W
Xbox Series X 1 ~200 W 200 W
Standing Fan 2 ~70 W 140 W
Refrigerator (medium) 1 ~150 W (avg running) 150 W
Energy Bulbs (LED, 10W) 10 10 W 100 W
Water Dispenser 1 ~550 W (heating + cooling) 550 W

BigDickProblems:


Found a solution to this by changing the cable that connects my battery and my MPPT controller just as @ HeavenlyBang had suggested. I cut out the new cable from one abandoned laptop charger, because I felt it’s also a Dc cable anyways.

Lo and behold, for the first time in a million years, got a current of 12.4Amps (from a previous 6.5Amps from the old cable). I don’t know if my MPPT is wyning me for now😂, but I just hope it stays this way.

Thanks a lot @HeavenlyBang

Observation
This means that PWM does not have the functionality of deducing internal resistance as the MPPT, cos obviously the PWM just throws all the currents (about 18Amps) coming from the PV into the old cable and makes it extremely hot when touched. Unlike the MPPT, which figures it out and sends a current suitable for the cable to charge without being extremely hot.
I stand to be corrected pls.

use a dc solar cable or battery terminal cables instead.

fuckboys:

Yeah. I’ll get a new one. The previous one was from Josh. It’s also a solar cable, but obviously not so great.

Welcome fellow enthusiast.

3.5kw 24V hybrid inverter (Welion, Sako, SMS, Growatt) - 350k
5 600W or higher-rated Solar panels (Jinko, Canadian) - 700-800k
24V 10kwh Lithium battery (Deriy, CWorth, SMS, Sako, DIY) - 1.3-1.6m
Installation materials and installation fee- whatever change is left will do this.

Make sure whatever item you're getting is genuine. Reach out if you need any assistance in getting them.

Thank you. Does the inverter come with the solar charger and controller? Can you help rank the inverter and battery from best to worse in terms of performance metrics - fast battery charge by solar, intelligent load balancing, intelligent inverter system, ability to monitor remotely via Wi-Fi, economical discharge on 80% to 100% load, etc?

Thanks, but I'm talking about real world capacity of both topcon and perc. I've seen reaults of a perc of 665w doing 700w, but topcon has sparse user reviews even thoug they say its an advancement on perc.
Anybody who has bought the jinko 590w recently from fouani, please whats the highest instantaneous power it has generated for you

Yea, options seem to be limited right now to topcon, so I want to see real world usage data on topcon to know if I should just get it right now or wait until the perc I need arrives Nigeria

My Jinko 580w panels have made about 97% rated power in the past.

Growatt 48v 6kw - ~500k

Not sure if there's a 10kwh Deriy pack but it's probably your best option here. You go need extend your budget to 3m last last but this should take you off-grid entirely.

Used 5KW Gennex Transformerless inverter still available.

I'm not sure about the battery, but Cworth and Felicity sell battery packs. Valto and Mrreed build packs as well.

Well, I have three 580w panels and a 550w in series, which should make ~2200w.

I make 1.8kw continuous on a good day of sunlight. So about 82% output, which is well within spec considering other factors.
