Thank you so much for mentioning this problem. I installed a Multiplus, 2 x MPPT and a BMV702 2 months ago, loaded ESS onto a RPI and thought I was good to go, well I can tell you the ESS did not perform as I thought it should, and having no previous experience with it I could not articulate my problem properly. The Min Soc, Scheduled Charge and just about everything else did not work properly. I eventually loaded node red and controlled the Multi this way. After reading this post I disconnected the BMV and everything is now working the way I imagined it should. It would appear that the B

Also managed to buy the last one at Builders in Witbank.....works awesome

My understanding is that the 2 x 335w will pull down the 7 x 405w to 335w. I have read that the panels will de-rate to the lowest Volts/Amps of the string.

Search for solpiplog on github. Nuno has an image for the rpi that has built in time and soc control....and it is completely free.

You are getting a low battery alarm and it would appear that your battery is not setup correctly. There is no way that 45.5 volt on a lithium battery gives an 81% SOC. Did you enter the correct values of the Revov batteries into the BMV? Running your batteries down to 41 volts is going to kill them in a short period.

Absolutely. I have a Narada that blew its BMS with a lightning strike last year, replaced it with a "Daly without comms". All still running fine. I am running 4 of them, first to busbars and then to inverter.

It is capable of running your whole house with the proper planning and due diligence by the occupants of the household. I had a 5kVa running for 3 years where we did not even know when the grid power was off most of the time. I did however split my DB into 2 and ran the whole house except for air-con, oven and back-up electric geyser. The 5kVa can handle these other loads as well, but the problem arises when you run the appliances concurrently. If you run the oven and the missus switches on the kettle, then the inverter would change over to grid feed. The funny thing is that I now am ru

I purchased a RPI3 B premium kit from RS Components for R1440. My Multiplus and 2 x MPPT charge controllers running smoothly so far on Venus.

I also have the 2015 model and it does not have the feature settings for lithium batteries. I run mine on "User" settings through a BMV702 which works great. Fault code 57 indicates a "Current Sensor Failure".

Thanks Chris. I have only given all the wiring a visual inspection. I will now check properly. Thanks

I am thinking that my 5kva Mecer/Axpert is on its last legs. It has lasted a good 3 years this month, but I am now getting a burning smell every time the wife runs the kettle. I opened up the inverter and can't see any melting/damaged components. Even cleaned all the highveld dust out. I recently purchased a Smart Victron 150/45 MPPT external controller for my extra panels and am so damned impressed, that I am now thinking of going all Blue. Besides, I want a device that I can set and forget for the next few years. My choice is now between a very well priced 2 year old Multi 3kVA and a br

I think the 48V starts from 150/35. https://thepowerstore.co.za/products/bluesolar-mppt-150-35?variant=12362627153982&currency=ZAR&utm_medium=product_sync&utm_source=google&utm_content=sag_organic&utm_campaign=sag_organic&utm_campaign=gs-2018-09-19&utm_source=google&utm_medium=smart_campaign&gclid=EAIaIQobChMIyLbpovPT6wIVg_uyCh3iZADlEAkYAiABEgLYP_D_BwE

I am now weary of the cheaper MPPT controllers after having just replaced the last fongkong one with a Victron. I certainly have peace of mind not wondering how long it will last. Here is a decent one for a few bucks more: https://www.weable.co.za/power/battery-equipment/mppt-charge-controller/victron-energy-bluesolar-mppt-100-50-vic-bluesol-mppt-100-50.html

Great work @JustinSchoeman

@plonkster I think I will make your day. My 5kVa Axpert has been running for 3 years, and it is busy serving its purpose well. However after learning about all the different inverters on this forum I will be replacing it with a Victron once it decides to give up the ghost. One soon realizes that there is no substitute for quality and longevity of a product.
