![]() ![]() I believe that a high end MPPT charge controller will make your batteries last longer and produce more kWh per useful life than investing in a BMS for any series or series parallel strings of any type of lead acid battery. Keywords: State Of Charge (SOC), Electric Vehicle (EV), Open Circuit Voltage (OCV), Battery Monitoring System (BMS). I also use a part of the potential of a monster Aims 12kW inverter to run my whole house for 6 to 8 hrs when the sun shines and keep the batteries above 70% state of charge unless I have to go deeper overnight in a power outage.SLA obviously don't require watering or equalizing but FLAdo stay well balanced if you equalize them every month or two.īack to your question. I installed a watering manifold on the batteries and I give them a drink about once a month. I have had really good luck with strings of 8 (8s)Trojan T105s and a Morningstar Tristar 60 MPPT fed by 6X265 watt Canadian solar panels. Spend your money on a custom configurable charge controller that can be tuned exactly to your solar/generator/turbine and exactly to the battery manufacturers specs. I would rarher prefer to monitor the batteries live.Ĭlick to expand.Possible? sure. Your suggestion of disconnecting each battery is a lot of work, and a lot of downtime each time I have to switch everything off, disconnect, etc, etc. When I go over to 2V cells, I would hopefully be able to reuse the same monitoring system if it can read as low as 1.8V. Getting back to your original statement about being able to monitor the cells. Aliexpress has some balancers for 12V batteries. for 2V, 6V or 12V batteries with M8 terminal connector. It uses a special Impedance Track (proprietary) algorithm from TI. ![]() This means that if the 24V section shows problems, I won't know which one of the two 12V batteries has a problem.īalancing them would be my next quest. With respect to capability at low temperatures, they do perform much better than lead-acid or NiMh batteries however, temperature management is prudently. BMS system designed for monitoring lead acid, lithium-ion or nickel battery blocks and strings. This IC is designed especially for Lead-Acid batteries. Victron has a monitor for this but it doesn't work well in a 48V environment since it only monitors three points, which in this case means 0V - 24V - 48V. The system can be operated with state-of-the art Li-ion batteries or traditional Lead acid batteries, which are still widely used on 95 of military ground. But if I could monitor all 16 batteries, reporting to Grafana, I would be able to pickup a problem before it gets out of hand. Since the batteries are sealed, there's not much I can do from a cell level. Ensuring full battery system operability, preventing unexpected or unnoticed faults caused. Different brands and models exist in South Africa, like the Trojan R105-E of Omnipower 200A, etc. Monitoring, regulation and alarm system for lead-acid batteries. EquaLink is designed to monitor and optimize lead-acid and other battery types in a given battery system. ![]()
