I believe
@MisterSandals and I have answered those questions already in posts #8 through #15.
To confirm, the Pylontech battery/batteries will inform the inverter the max rate to charge or discharge, up to any limit you set on the inverter. The RHI can only charge at max rate of 62.5A anyway.
Indeed you have.
I ask Bing AI for recommended AMPS rate and this is what was said:
Thank you for providing more information about your battery.
According to the web search results, the RHI-3.6K-48ES-5G battery is a hybrid energy storage inverter with an integrated DC switch, compatible with both lithium and lead-acid batteries12.
The nominal energy of the battery is 3600 Wh and the voltage is 48 V23.
The maximum charge and discharge power is 3 kW234.
Using the formula from my previous answer, the recommended charge and discharge rate in amps for this battery is:
rate (A)=capacity (Ah)×C-ratevoltage (V)rate (A)=voltage (V)capacity (Ah)×C-rate
Since the capacity of the battery is 75 Ah2, we need to find the C-rate. One way to do this is to divide the maximum charge or discharge power by the capacity and voltage.
For example:
C-rate=maximum charge power (W)capacity (Ah)×voltage (V)C-rate=capacity (Ah)×voltage (V)maximum charge power (W)
C-rate=3000 W75 Ah×48 VC-rate=75 Ah×48 V3000 W
C-rate=0.83 CC-rate=0.83 C
Therefore, the recommended charge and discharge rate in amps for this battery is:
rate (A)=75 Ah×0.83 C48 Vrate (A)=48 V75 Ah×0.83 C
rate (A)=1.29 Arate (A)=1.29 A
This means you should set the charging current and discharge amps to 1.29 amps for this battery.
However, this is a very low rate compared to the maximum rate of 62.5 amps that the battery can handle2. You can increase the rate up to 62.5 amps, but this will reduce the lifespan of the battery and increase the risk of overheating. Therefore, you should choose a rate that balances your power needs and battery health.
I hope this helps you set the charging current and discharge amps for your RHI-3.6K-48ES-5G battery. If you have any follow-up questions, feel free to ask me. ?
And for the battery spec it says:
*: The recommended and max. continuous operation current is for a battery cell temperature within 10~40°C to consider, out of such temp. range will cause a derating on operation current.
I was getting conflict from the inverter set up with the battery set up -
this happens when you are rookie.
In conclusion I don't need to change to 50A as inverter is limiting to 62.5A anyways which is what you peeps were saying!
