High voltage alarms; Hi been running Quattro inverter with 6 pylontechs for 3 years. Few months ago had high voltage alarms signals when batteries reached 100%. Found 1 battery swollen. Firmware on batteries and all components were updated. Now struggling to get batteries charged. If there is no loads solar production drops.

Microgrids are becoming increasingly important for improving the dependability, stability, and quality of the electrical system, as well as for integrating renewable technologies.
Just completed our first travel trailer trip of the season. Towards the end of each travel day we got multiple notifications from the SmartSolar Charger of high input voltage. This occurred on 3 of our 5 travel days - all between 5-8 hrs long. There were multiple days of running solar only at our various campsites with no issues.

In a DC microgrid, the crucial part of a DC distribution system is the DC-DC converter. To establish a competent renewable fed DC distribution system, proper selection and design of DC-DC converter with high voltage step up and high power handling capability is essential .
The BMV has the high voltage alarm threshold set at 14.7 and clearing at 14.5. I am contemplating setting the threshold to the fast charge voltage of 14.9. The only thing that I can think of as being different is that the water temperature may be lower (about 11 degrees C) than when we commissioned the system.
High temperature alarms are generally caused by a too high ambient temperature, often in combination with a high inverter load. Check if the area the inverter is used in, is well ventilated

I have six 100 watt solar panels on the roof of my off-grid cabin. I have been using lead-acid batteries with an 80A PWM charge controller. Charge voltage had been set at 13.8V. I want to swap out the lead-acid batteries for a 300AH LiFePO4 battery. I reset the charge voltage to 14.4V. I...
The problem in this case, however, is that there is a high voltage alarm at a much lower voltage (3.45V per cell), which could possibly indicate an imbalance. One thing you might try is to configure the Multi to 53V, and the solar chargers to 53.2V, then turn off DVCC (and do a VE.Bus reset) and let the Multi/Solar charge the battery nice and high.

That high battery voltage alarm is actually a high cell voltage alarm, sent by the BMS. Most likely cause, first thing to check, is cell imbalance, which in itself is not a problem
With the weaker grid strength, the PCC voltage becomes more sensitive to the power exchange between the MG and the utility grid compared to a strong grid scenario. To maintain the PCC voltage within prescribed limits, the BESS provides voltage support by absorbing reactive power during peak solar generation periods on days 2, 3, and 5.
The problem is that I constantly get a high voltage alarm in cell 5. I measured with a multimeter and each battery is exactly 4.19v.

High battery voltage alarms appeared straightaway along with the loss of PV inverter monitoring as previously posted. I reverted back to v2.51 and the high battery voltage alarms disappeared but I went back to exceeding my grid feed in limit. Updated to v3.50 and PV inverter monitoring was restored but high battery voltage alarms returned.
The renewable source, photovoltaic panels, are also connected to DC bus by means of a DC/DC power converter. Additionally, the microgrid includes a hydrogen-based backup system, integrated by an alkaline electrolyser, a PEM fuel cell, and a medium pressure hydrogen storage tank.
5. Conclusions The implementation of RES-microgrids with high voltage DC-bus involves the use of batteries as an energy storage system. This allows mitigating the main drawbacks associated with the stochasticity of most of renewable resources.
Regarding the scientific literature, a huge number of RES-based microgrids present a connection scheme similar to Fig. 1. That is, there is a high voltage-DC bus supported by the battery bank as ESS, and additional renewable sources (photovoltaic panels, wind turbines or fuel cells) are connected to DC-bus by means of DC/DC power converters.
