When I bought mine, there was no remote access. In both cases, they are rather poor at remote monitoring. My new setup will properly shut off loads when the battery is drained. It does not need amp specific components. I like that approach because the BMS is simpler. It sends signals to the loads and to the chargers to shut off when necessary. The Electrodacus solution makes the BMS a monitor and controller. In my mind the only benefit to MPPT is that you can have a high voltage coming off the panels, and thus cheaper wires, and that all depends on your physical layout. Those are 2 factors that mean that in order to justify MPPT, you have to prove that 1) it is worth the money, and 2) that large heat sink is somehow not throwing away solar energy. I am not an expert on MPPT vs PWM, but the PWM controller is cheaper, and does not need a large heat sink. I am sure that I can use the SC-2030 to charge the Li batteries, but I still need a balancer, and Electrodacus provdes that, so I'm going to sell the bogart stuff. LiFePo4 charging is much simpler than lead acid, and thus the SC-2030 logic is unneeded. I am not an expert, so I cannot confirm that his solution is excellent, but it makes sense. It is essentially sends the panel straight to the LiFePo4 cells, but will respond to the main controller. Both prefer PWM type controllers, although my understanding from Dacien is that his solar controller DSSR20 is not really PWM or MPPT. Both seem to be providing products that they created for themselves. Both are excellent at responding to emails. It feels like Dacien at Electrodacus is virtually the same as the people at Bogart. I am replacing the TM and SC 2030s and the batteries with and the Xuba 280ah LiFePo4 cells.
Bogart battery monitor upgrade#
Bogart offered an upgrade to the firmware, but I would have to mail it to them and pay. My Victron multiplus compact 24/2000 does not like that excess voltage and shuts off. The SCC shuts off at the target voltage, but the battery cruises past the target on to 33+ with some sort of momentum. I think this means that the SCC sees the voltage at 27 and increases that to the proper float value, then the battery responds by slowly ramping up it's voltage. Bogart replied that this is caused by sulfation in the batteries and there is not much they can do to fix it. Now, when they are at 100% and the sun is shining, the voltage will cycle from 27 to 33 volts over the course of many seconds. I left the power on in the winter and dragged down my AGMs to 10%.
Bogart battery monitor update#
A method of firmware update is essential for any product that has firmware. I would also suggest they add the ability to update the firmware. I would also suggest to Bogart that they provide signals from the TM/SC that can be used to shut off loads when the battery gets too low. I went with Bogart because, as they said above, they do "amp-hrs counting to determine endpoints ". I have an SC-2030 and TM-2030 for the past 3 years.
