Has anyone tried this battery case from Luyuan for a 16s build with EVE 280Ah?

Hello, I have a 100Ah 2p8s pack made of EVE 50Ah cells I recovered from a commercial rack pack. The bus bars appear to be welded or glued to the cells' terminals so no way to reconfigure the cells. I performed a top balance by charging each pair of cells to 3.65V with a bench PS (while they are...

Reviewing the document below, specifically the note about the accumulation / saturation / absorption stage on page 5, I notice that most popular all-in-one inverters (Deye / Sol-Ark, MPP Solar, LuxPower...) do not seem to have a setting for the accumulation stage cutoff. They however all have a...

Has anyone managed to get their Deye inverter to accept data from one of the RS485 CT clamps available on the market? The compatible inline smart meters are not a good option for me due to wire size and also because a non-invasive solution is much preferable. Analog CT clamps are not an option...

I have established communication with SA's MQTT server via Mosquitto but all the values I am getting are limited to one decimal place. Is there any way to adjust that?

I have a Deye 8kW inverter. Since I have no net metering, I set it up to use the battery power at night. However, I noticed that the inverter continuously pulls 1.3-1.6A from the grid (300 to 370W) at night AND this power does not seem to be accounted for in the metrics. Any clue? See attached...

Hello, I am confused by the AC section of the Deye spec sheet and manual. My case use is the "basic" mode from the manual minus "on-grid home" since there is no net metering here. Therefore I want my whole house to be the "backup load". 8kW continuous and 16kW peak is comfortable for my needs...

Hello, Is it possible to run the Deye as an offgrid inverter and only switch on the grid when needed to charge the batteries? I see in the battery setup that there is a "grid signal" feature, which could potentially be used to control an external "normally open" relay or contactor to connect...

So I have this 63A dual pole DC breaker and I want to make it a 126A breaker to protect the positive side only. Can I wire it like this to achieve the intended effect? (wires coming from + pole of the battery)

Two of my freight forwarders told me they could not accept LiFePO4 cells for shipping since Aug 1. The second one told me it is because of a crackdown by Chinese customs on dangerous goods in ports. He sent me the below text...

Hello, I am new here and new to solar systems. I have an engineering background and decent basics in electricity. I am from Belgium but I live in the Philippines (single phase 240V, 60Hz). Our electricity provider is expensive, unreliable and does NOT offer net metering. We experience blackouts...
