This also going to affect the integrated amp-hours, making them read a bit high.Ĥ) (same thread as #3) They got about 99.8% good rates. The power supplies regulate at 12 amps but after a short time will display 12.5 amps. It works well but seems to read a bit high in current as the shunt heats up (indicating the shunt material is not optimal). This forum has lots of support for this meter, including some re-written and expanded instructions hereĢ)Great meter, easy to calibrate and set alarms, top of the line construction.ģ) Here is one of the original meters in this thread being used for charge monitoring. If i find i need much more accuracy then i might invest in something better but this may just do the trick for me. Mine also tends to bounce around a little when it has no load on it, not been able to sort that out just yet.So is it worth it? For me it was, i had nothing to start with and now have something. It doesn't appear to have any intelligence in it for that. The other features like the AH counter works on you telling it the capacity of your battery and then simply counts them out and back in. Volts wise it seems good, Amps it needs a little bit of messing about with to get an accurate reading. What i would say is that you need to calibrate it so if you are looking for something to work straight out the box then don't buy. Here's the manual in pdf.ġ) Well i decided to get one and it arrived in a couple of weeks. SH-100-100 Shunt is typically only used with amperage loads under 70 Amps and where need to measure down to 0.01 amps.Cheaper here and they've sold about 200 more. See SH-500-50 Shunt for most loads (70+Amps), measuring down to 0.1 amps. Contact us if you wish to special order without the Fuse and Fuse Holder (TM-2030-A). Use a 2-gang electrical box if you wish to mount on an enclosure. It is easier to view and enter programmed parameters. The newer TM-2030 includes better lightning protection compared with the TM-2020. (For the technically knowledgeable only) The TM-2030 has a serial data output of all the real time data-which could be used to access data for other control or output in, for example OEM applications. The TM-2030 has a simplified level of operation suitable for most users, but can be configured for more flexibility (and complexity) where occasionally required. The TM-2030 can also monitor the voltage only of a second battery, such as a starting battery, or possibly also the input voltage of a solar array (if less than 100 volts.) This also provides lightning protection for the TM-2020. The TM-2020 will operate with 12 or 24 V systems, but requires the addition of the TM-48VA Adapter and lightning protection board when using it with 48V battery systems. The TM-2030 will operate with (nominal) battery systems from 12 to 48V. The TM-2030 has some minimal data logging, which can be useful for a technician to diagnose some common setup or operational problems with battery systems. The TM2030 is easier for you to program the necessary system parameters: How many days since the batteries were fully charged: to remind you to not wait too long between fully charging your batteries to maximize their life. Volts of the batteries, for example to check that they are being charged at proper voltage.Įnergy going in, or out of your batteries, measured in amps or watts, so you can see that your charging sources are charging properly, or how much current your loads are using. Percent Full (State of charge) of your batteries, so you can see if you need to charge them more, or check that overall usage is less than your charging resources. All models are designed to monitor the following: Some systems may already have a Shunt installed. All for under $200 with a shunt (which is required but not included, see SH-500-50 or SH-100-100). They will help you maintain your batteries. The TriMetric is used to monitor battery systems used in remote homes, RVs or boats that have batteries that store solar, wind, or possibly generator powered chargers. The older models (TM-2025 and TM-2020) are still supported and available by special order. TriMetric TM-2030 is available in two models:TM-2030-RV and TM-2030-A. Can also be used as a stand-alone monitor. Very similar to the TM-2025, but can now work in tandem with their new SC-2030 controller for optimized battery life, capacity use and efficiency.
