Good evening experts,
Please which inverter would be best for my home usage out of Schneider SW4024 & SW4048? Also, what's they minimum capacity of LiPo4 battery bank that would be required? Are these inverters hybrid?

swagifted:
competition on fire....lets continue till we get back to 15kwh for 1.5million naira and less....i know we can do it...everybody should continue to patronise the naira till we hit 1k naira per dollar ...patronise MRS filling stations

waleayeni1:
Please is there any reason why no one is looking at my question? If i offend make una forgive. Please help.

solasola:
Its better you share pictures of the display.
Is there communication between your inverter and the battery, error 04 should be low battery though..... Follow the advice given on setting up protocol 05, and make sure the communication cable is connected correctly, i mean. There is a particular end that goes to the inverter and battery, if interchanged, it wont connect. Hope this helps a little.

Probably because most people here don't have hands-on experience with Schneider hardware.

I can testify to the assertion that this inverter can power many appliances.
I have the 3000w which I currently use to pump my 0.75hp submersible pump .

burnerr:
day 3 of having this battery configuration issue. The battery is showing as low while the inverter reads 53.9V. I've tried everything I've seen online, and the shinewifi dongle isn't coming up at all when plugged to the inverter.

If anyone has any suggestions, I'm all ears.

I have a 4048, will advise you to get that instead of the 24 version (4024) simply because it's easier to run high capacity lithium battery in 48v instead of 24v. Both are same capacity though just different battery system voltage.

Also you get to run higher number of solar panels in 48 configuration rather than 24v with same solar charge controller.

There is no "minimum number" in battery configuration. You buy battery according to your load needs. You can get a 500wh lithium battery in both 24v and 48v. Same inverter can also work with a 60000wh or 60kwh battery.

Using generator analogy, your inverter is the generator, your battery is the petrol. The amount of fuel you buy is dependent on how long you plan to use the generator. This is applicable to inverter too, size of battery depends on the load to be powered and the duration you want it powered.

12 hours.

Two jinko 555w panels - 250k
Find a small 12v hybrid inverter to buy from brands like Sako, Welion, CWorth - 250k
Powmr 100aH battery -290k
Accessories and installation - 150k

Put the inverter in power saving mode so it doesn't invert if it doesn't detect a load, then buy a timer for the freezers.

You can run on solar from 8 am - 5 pm, which is 9 hours.

Set the timer to come on at midnight and go off by 3 am.

My ~200L chest freezer draws just 110w. Even a 300L freezer shouldn't take more than 150W. Two of them 300w. Three hours of use should have the battery down to about 25% of charge.

Twelve hours of runtime daily, and your freezers remains frozen for 24 hours.

realpoacher:
Guys I need a modest quote for a max load of 600 watts for 5 hours daily.
I want a LiPo4 battery please.


I intend to charge the battery with solar panel and light (whenever NEPA is available).

Thanks

bkuranga:
Thank you once again.
So I revisited this, and I'm lost somewhere.


What capacity of hybrid inverter do you suggest?
I have searched, most that I have been seeing are 24V and not 12V.

HeavenlyBang:
Valto has 12v hybrids for sale.

KA24DETT:
LOL.. thats not true. it will clip. I do run my 10kv hybrids with 33,000 watts of solar panels connected. MPPT pulling 120amps from dawn to dusk. One year and still working. In my system, none of my systems have less than 30,000 watts of solar panels attached to it and i have 8 systems running. I can attach videos.

Also, read this and follow up instructions carefully


Error 04: This indicates that the inverter detects the battery voltage or State of Charge (SOC) as too low. It could stem from an actual low battery voltage, a mismatch in settings, or a communication issue affecting voltage readings.

Error 20: This points to a BMS (Battery Management System) communication failure between the inverter and the Hope 5.5L-A1 battery, often due to incorrect settings, faulty cabling, or compatibility issues.

Since the Hope 5.5L-A1 is a Growatt branded battery, it should be compatible with the SPF 6000ES, but proper configuration is key to resolving these errors.

Recommended Configuration Steps
Here’s how to configure your system:

1. Verify Physical Connections
Battery to Inverter: Ensure the battery power cables (positive and negative) are securely connected to the inverter’s battery terminals, with no loose connections or corrosion.
Communication Cable: The Hope 5.5L-A1 typically uses a CAN bus for BMS communication. Connect an RJ45 cable between the battery’s CAN port and the inverter’s BMS port. Use the cable provided by Growatt, as pin assignments matter (e.g., CAN-H and CAN-L must match).
Battery Breaker: Confirm the battery breaker is ON and the battery is outputting power.

2. Check Battery Voltage
Use a multimeter to measure the battery voltage at the terminals. The Hope 5.5L-A1 is a 48V nominal battery, so a healthy voltage should be between 48V and 54V (depending on SOC). If it’s below 42V, it may need charging via solar or grid before the inverter can operate properly.

3. Inverter Settings
Access the SPF 6000ES settings via the LCD display and buttons. Adjust the following parameters (refer to the SPF 6000ES manual for navigation):
Program 05 (Battery Type): Set to “LI” (Lithium) to enable BMS communication. Since the Hope 5.5L-A1 is a Growatt battery, select the appropriate lithium protocol:

Likely L01 or L03 (specific to Growatt ARK/Hope series). Check the battery manual or contact Growatt support to confirm the exact protocol code for the 5.5L-A1.

Avoid “USE” or “US2” unless BMS communication fails entirely (more on this later).
Program 02 (Max Charging Current): Set to a safe value, e.g., 60A-100A, depending on your battery’s specs (Hope 5.5L-A1 typically supports up to 100A charging).
Program 01 (Output Source Priority): Set to “SBU” (Solar-Battery-Utility) or “SUB” (Solar-Utility-Battery) based on your preference.
Program 12 (Battery Low Voltage Cutoff): Set to 42V-44V to prevent deep discharge.
Program 13 (Battery Back-to-Grid Voltage): Set to 48V-50V to ensure the battery charges adequately.
Program 19 (CV Charging Voltage): Set to 56.4V (default for most 48V lithium batteries, including Growatt’s).
Program 20 (Float Charging Voltage): Set to 54V or as recommended by the Hope 5.5L-A1 manual.

4. Test BMS Communication
After setting Program 05 to “LI” with the correct protocol, restart the inverter by turning it off and back on.
Check the LCD for battery SOC and voltage readings. If Error 20 disappears and SOC displays correctly, communication is established.

5. Troubleshooting Errors

If errors persist:
Error 04 Persists:
The battery may be too discharged. Charge it externally (via solar panels or a charger) until it reaches at least 48V, then reconnect.
Verify the inverter’s voltage reading matches your multimeter. If not, there may be a wiring issue or inverter fault.

Error 20 Persists:
Double-check the RJ45 cable integrity. Swap it with a known working cable if possible.
Ensure the battery’s firmware and inverter’s firmware are up to date and compatible. Contact Growatt support for the latest firmware if needed.
As a fallback, set Program 05 to “US2” (User-Defined without BMS). This disables BMS communication and relies on voltage-based control. Adjust Programs 19 and 20 as above, but this is less optimal for battery health.

6. Additional Checks
Battery Health: If the Hope 5.5L-A1 has been deeply discharged repeatedly, it might be in a protection mode. Reset it per the battery manual (usually involves turning it off/on or pressing a reset button).
Inverter Logs: Review the inverter’s fault log (if accessible) for more context on when Errors 04 and 20 trigger.

Next Steps
Try these steps and monitor the system. If Errors 04 and 20 still occur, let me know:
The exact battery voltage you measure.
Whether the BMS communication works after setting “LI” with the correct protocol.
Any additional behavior (e.g., inverter shutting down, alarms).
This should resolve the issue, but if not, we can dig deeper into hardware or firmware causes. Let me know how it goes!

Why did you say avoid use 2, is it for his specific problem or generally??

Nteogwuija:
Hi, guys. So I did a parallel connection of 3 350w panels, with each having a maximum current of 13.6a. And I've noticed that whenever the sun is very high my DC breaker would go off and the system will stop charging. I'd have to turn it back on b4 it resumes charging.

The wire is a 4mm² coated wire.

Please, what do I have to change to rectify this?
