The controller is not operational 5.3. Solar issues 5.7. educational information on lead acid battery monitoring, with charger set level . At default my charge controller is set to charge my batteries to 13.8v float, 14.2v Equalizing. When the unit is powered up the next time it will again perform the initial automatic voltage detection. Absorption time US Battery specifies is 2-3 hours. 4) 1.25 is typically fine. As you have two batteries, no more than a 50 amp rated charger. PaulRainbow said: I have SLA batteries and find that charging with solar, via a Victon MPPT controller,absorption voltage of 14.6v and float of 13.6v works well for me, i'm onboard a lot. Keep the other one as a spare. If a cloud comes past and you go back to bulk prematurely (but stay above 12.6V) you may only get one sixth = 30 minutes before it hits float. Do not want to screw it up. MPPT 75/10. But, even worse, it seems that if the battery momentarily encounters a charging current that is above specs, it will turn the charging completely off. When the battery voltage drops substantially below this level, due to a high load for example, during at least 1 minute, a new charge cycle will be triggered. I'm a bit concerned that you don't have enough PV power to properly charge a battery bank of that size. 0 Likes 0 Show . Hello, I got . Once the firmware update is complete, go to the settings page on VictronConnect. Depending on the state of charge (SoC), the cell may temporarily be lower after discharge than the applied voltage. However, 'managed' lithium batteries require specific communications (Can . #2. You Do want to limit the charging amps to about 25 amperes per each battery. If you connect a model with recent firmware, this option will no longer be shown. In fact I've just fitted one to my motorhome, along with the required Smart Battery Sense, due to the fact the leisure battery temperature location when compared to the location of the controller can have a difference of up to ten degrees. . Where US Battery gave a range for charging voltage, I selected the midpoint. The settings vary between battery manufacturers and models. Thought this would be fairly simple! 6 Sep 2019. This is causing the early resets. On the settings page click on the three vertical dots in the upper right corner and select "Reset to defaults" from the drop-down menu. Right now the controller only shows a flashing float light. That would be 2-6A in your case. Once you come to this main screen, select the battery preset menu and choose "User Defined." 8. Cannot find preset default settings for lead acid batteries. The Victron Charge Controller is a Premium Choice for PV Offgrid systems. Equalization Voltage: 2.6-2.65 VPC. Check out our video, where we go through how to set up the BlueSolar charge controller along with out Battle Born Batteries. and trying to charge lc-r123r4pg. What the current settings are saying is anytime the voltage is above 0.0 v and you are charging less than 4% of 390a = 15.6a reset to 100%. The 5V start requirement can delay your hours of usable sunlight considerably. You referred to the Varta LFD90 yet when this was first produced it was stated on Varta's own website this battery was for low to moderate use. Specific information about compatible batteries that have been tested and are supported: Aquion AHI AXIstorage 7S/9S BattleBorn Bluenova Energy Storage Float During this stage, float voltage is applied to the battery to maintain it in a fully charged state. The Exide ET650 as an example and also a L/A battery is 26.5 KG. And that there would be a generic lead acid profile in the MPPT controller (there are only gel and LIPO) Click to expand. In this video, Johannes explains the varies ways to extend the life of a lead-acid battery. Lastly, inside the User Defined settings menu you need to make these changes: Check the manufacturers data for your battery. Needs to be set per your battery manufacturer's recommendations (note: 14.6V maximum for LiFePO4 chemistry). I did tweak the float voltage for mine as 13.8V was slightly too high for long term float charging on my Varta leisure battery (e.g when sat on the drive for a few weeks). Always fix the battery voltage when connecting the MPPT behind a Cyrix-Li-charge relay. Six was the default set by Victron. Also setting temperature compensation to following: -30mV/C, absorption duration fixed, absorption time 3 hours, 4A tail current. Please consult the documentation for your particular batteries as to charge parameters. Discharge floor The "Discharge floor" parameter is used in the time remaining calculation. I set it for six, however, for two reasons. More information about the cable can be found in its manual. . Why did you set up the battery monitor with only a 50% discharge floor if you can utilize almost the entire batteries capacity since it's a battle born? If anything is unclear or if you have additional questions, please give us a call at (855) 292-2831 or email us at info@battlebornbatteries.com. I saw this blog and it helped me set up my LiFePO4 battery but I do have one question. Operation issues 5.10. This is the recommended charge algorithm for lead acid batteries. Once the firmware update is complete, go to the settings page on VictronConnect. And, US Battery indicates that the battery itself will provide feedback as to how long it needs to stay in the absorption stage. Setting Float to 14.2V will damage your batteries. This is by far the best MPPT charge controllers for lithium batteries. Once it starts working, it will continue to work with a voltage difference of only 1V. If you are confident going to expert mode, modify the settings and set the absorbtion voltage to 14.2 volts, float voltage to 13.4 volts, absorbtion time to 30 minutes. There is a default lithium setting for lithium in the Victron unit, select that for a start. From Vision 6FM100P-X spec sheet Cycle Use = 2.4 to 2.45 VPC = 14.4 to 14.7 per 12v battery = 57.6 to 58.8 per 48V bank Standby use = 2.2 to 2.3 VPC = 13.2 to 13.6 = 52.8 to 54.4 per 48V bank All Activity Home In lead-acid batteries, the battery voltage drops significantly as you use them. The fixed or adaptive mode can be chosen on the battery settings (Victron unit). 29 - 48V cut-off sounds about right, you may need to drop slightly if you have heavy loads which cause short term voltage drops. Or find another standard AGM charging parameter and use that. IMO 24 KG is at the lower end of the scale for a good L/A leisure battery. Set MPPT for 4A (0.02C) and configure shunt for 4% 6) Use the cycle use . When the unit is powered up the next time it will again perform the initial automatic voltage detection. One of the most basic functions of a battery monitor is to display the remaining charge of your battery system. Batteries are overcharged 5.6. Communication issues 5.8. The Victron range of inverters are compatible with a wide range of lead-acid and lithium battery systems and the Victron MPPT solar charge controllers are fully programmable to match the charging parameters of almost any battery on the market. The battery monitor calculates the time it takes until the set "discharge floor" has been reached. 1,260. I need the correct settings for the rotary switch. It is also used to set the state of charge alarm defaults. Unlike battery inverters, most MPPT solar charge controllers can be used with a range of different battery voltages. Victron Smart Battery Sense measures only temperature. For example, most smaller 10A to 40A charge controllers can be used to charge either a 12V or 24V battery , while most larger capacity, or higher input voltage charge controllers, are designed to be used on 24V or 48V battery systems. a - Modify absorption voltage b - Enable/disable batterysafe mode Switch on or off the batterysafe mode, please note that batterysafe mode has been removed as of version 1.13. Then, plug a VE.Can terminator in the other VE.Can socket on the GX device. Batteries are undercharged 5.5. This voltage drop typically gives some indication that your batteries are running low. Battery Compatibility. Rotary; Sep 14, 2022; Lead Acid Batteries; Replies 4 Views 155. For example, your lights may dim as the batteries get low. Sep 14, 2022. Two VE.Can terminators are included with the package of the GX device as an accessory, only one is used. How temperature, how much you charge it and how fast can all have. On your SCC, the Absorption voltage is called "Boost Charging Voltage" because they prefer to make things difficult for you. If Renogy gives different capacity ratings for 100 hours, 20 hours, 10 hours, etc., Victron has a Peukert calculator.
