Re: Solis Cloud App - utter misery

Mine has been working fine, both Android app and on the web. I was "offered" an update but refused, "if it ain't broke don"t fix it"

Screenshot from today.

Re: Solax sk-su3000e - Pylontech us2000c Battery BMS and CT Clamps - start again

Think you are on a hiding to nothing trying to get the Solax inverter to communicate with the Pylontech batteries. There are numerous pleas for help on t'interweb on other forums and there is a long thread on this forum - none have a conclusion. This is the thread on this forum: (worth a read as at ...

Re: Solax sk-su3000e - Pylontech us2000c Battery BMS and CT Clamps - start again

As kommando says, seems like the BMS link is not working. Ideally this should use the CAN bus . Most common reason - assuming you have the correct battery selected on the inverter, is the cable is wrong. CAN bus only uses 2 wires - similar to RS485 - They need to be a "twisted pair". As fa...

Re: Solis Hybrid Inverter No Battery alarm

Yes, setting the charge current on the time of use page only sets the charge current for those times you want it to charge. Force charging has its own setting for SOC to start and max grid power (i.e. charge current). I think you have been lucky the fuse survived this long. It probably has not gone ...

Re: Solis Hybrid Inverter No Battery alarm

The fuse carries current both ways, charge and discharge. 50A is too small for a 3.6kW inverter. If the inverter is supplying a house load at its full capacity - 3.6kW then it will be drawing 70A from the battery and through the fuse, 1.5 times its rated current. The fuse will survive quite a long t...

Re: Monitoring Battery Capacity

151Ah @ a nominal 50V = 7550Wh or 7.55kWh

Only real way is to "coulomb count" or fully charge and then measure how much energy you can extract when discharging form full charge to your lower limit.

Re: Solax sk-su3000e OFF MODE following install

Just press and hold the "ENTER" button for 5 seconds to clear OFF MODE. It is mentioned in section 6.8 (page 30) of this manual.

Re: @marshman editing a load of old posts.

Thought I really ought to do the forum the courtesy of an explanation. I am leaving/have left the forum. It is a course of action I have been considering for a long, long while. There are several reasons but they can be summarised by saying that the general "morals" and "ethos" o...
