I appreciate this guidance. Thank you. I will do some noodling on the numbers.

Hmmm, This is a reasonable option for the price and would replace the MPP unit I have. And you are happy with this unit? I am looking for a technically wise and cost effective upgrade to improve my ability to charge. Consensus is more panels. so its just selecting the best SCC config to add...

In reviewing my Scc options, the most common limit is the 150-160 Voc. What is the magic here? With the higher capacity panels such as my Qcells I am limited to 3 panels in series, at which point I must either get another scc or spend more on a higher Voc rated scc. Faced with this choice what...

There is a plan in place to improve the “view”!?

Yup! Definitely getting that mesage

To summarize, the replies I have received (thanks everyone for the thoughts and questions!) -Keep AIO. -Add a separate SCC with matched additional panels to optimize the max Voc of the SCC to improve charge efficiency / reduce charge time of existing battery. -I did not hear that I should...

Thanks for this, The consensus seems to be a second separate SCC with more panels. Should I stay with the Qcell panel models and match a SCC to the additional ones? Any specific recommendations would be welcomed.

You are correct, the Bosan cells are 280 Ah capacity. I was curious to know if re configuring my cells into 2 - 12V batteries in series would be a better config that the config I used? Your calculations of recharge time is accurate based on my experience. - 90% 2 days and 1 day at 55%. We have...

Fixed. Thanks.

I have an off grid system That is not performing well at all. Battery seems to charge but takes a significant time to replenish. I have limited the load on the inverter to a single refrigerator with no other loads. MPP unit seems to draw a significant amount of power in no/small load...

Also, I had set the charing amps on the AC input to 30 amp but also tried 40 and 60 amp

It is a gas powered generator 60hz 120V output. As mentioned in earlier post the MPP display indicated it was receiving between 119 and 124V input before the Code 08 appeared and shut down the charge controller and the inverter. It reset 2 times and on the 3rd time if would not reset and I had...

I am exclusively off grid. No local power utility available. Its configured to accept 120V AC as input. MPP charge controller can be configured for either 110 or 120V and yes. 2P8 S is correct. 16 cells connected as 8 serial groups of 2 parallel cells

West Kootenays in British Columbia. I posted my configuration in my profile.

I did notice that the AC voltage registering on the panel when the generator was connected was ranging from 119-123V. Could this be the reason for the code? Maybe my generator is not producing a consistent (or consistent enough) AC voltage?

Here is a page from the manual PIP-LV 3KVA manual-20200907 with the fault codes... note the fault I get is 08

I have not opened it up but this is an option that I will try. I will also reachout to watts247. I did submit the issue to MPPSolar as well.

MPPSolar LV 3KVA-24V Inverter-Charger Error Code 08 This code as appeared 2 times and then seemed to reset. Then, on third appearance it will not reset. I have switched it off and on to try and reset. NoGo. As a result no charging or inverting is possible. The manual indicates this is a DC bus...
