Bogart Solar Controller...Comments?

I bought a Forest River Grey Wolf Cherokee 19RR Toy Hauler and I will be adding solar. My truck camper had a 120w panel and a Morningstar PWM controller and a Bogart Trimetric monitor system. Worked fantastic with one battery and the minimal demands of a truck camper. This TH will see more people in it and more off grid demands.

My plan is two batteries (12v) and two 140 watt panels.

For control and monitoring I'm planning on the new Bogart SC-2030 solar controller and the
Bogart TM-2030A monitor system. I'll also have a Xantrex ProWatt Sw1000 inverter which I used in the TC with great results.

Anyone have any experience with this controller? Any comments on what you read below?

Thanks!

SC-2030 SOLAR CHARGER — 30 AMPS MAX- 12 OR 24V PWM TYPE

The SC-2030 Solar Charger, working with the TM-2030 battery monitor has unusual benefits that can extend the life of your battery system. When designing the SC-2030 we checked many battery company websites, and spoke with experts in their companies to find out what they recommend for charging before we designed it. Many solar charge controllers have very limited ability to adjust--a few even charge with voltage that is lower than what any battery company recommends.

As a result of this research we've added two unusual features to insure that batteries are not damaged by over or under charging:

1.Amp hour counting: During a discharge period it measures precisely the amount of previous discharge, and then when recharging adds back the same amount plus an additional measured percentage of charge: for liquid electrolyte lead acid batteries about 110-120%--or for AGM types about 104-109%.

2. Also unusual in chargers, but frequently now recommended to maintain battery capacity is an extra higher voltage "mini equalization" finishing stage. During the last part of the charge it can increase charging voltage (at a regulated low current value) to avoid undercharge during a limited solar day. (This is sometimes called "IUI" charging.)

To match any battery type it has 8 adjustable charging parameters. To make installing these values easy, select one of 18 "battery profles" which will automatically install all these values for your particular batteries. After doing this, experts with special requirements may modify any of these.

All this is controlled by the TM-2030 Battery Monitor located in your living area--connected with a common phone cable to the SC-2030 usually located near the batteries. So in addition to high quality charging you also get all the benefits of the TM-2030 monitoring system: volts, battery amps, solar amps, extra unused power, replaced percent of charge compared to previous discharge, extra unused solar power, battery temperature and more.
  • Same trepidation regarding the BlueSky controllers with the IPN-ProRemote, but they do work together.
  • We have the bogart system including temp censer and it works great, also checked with hydrometer and not had to ad a drop of water in 4 months. Amazing people who haven't oven botheret to read anything about a product rubbishing it.but then they know everything.
    Frank.

    If the solar controller by itself-- nothing to do with the Tri-- has adjustable voltages and timings, then that can make it superior to others which don't.

    Their controller doesn't have anything adjustable, by itself. Fixed 13.2 Float, and 2 choices of V Abs - 14.2 or 14.7. Without a Tri it would've been inferior to most any other charger.

    But since the OP is going to buy the whole farm - both Tri and controller, it's different. The "brains" of this pair are in the Tri, so to speak.

    PS: few more thoughts.

    ... a "matching" controller, so that controller depends on the Tri to be right...

    You're onto something here. It's a very basic controller that is, in turn, controlled by Tri. Now, I don't remember all the bells and whistles of the Tri, BUT, if the adjusting commands in this combo are triggered by Amp-Hr counter, this is good - though might not be the best.

    My MPPT controller terminates the Abs stage when charging current drops to certain level. Still not perfect 'cause there can be loads affecting the current, but better than a fixed Timer. In my controller the Timer is still adjustable manually, forcing it to transition to Float when Timer expires, no matter what the charging current is.

    So... if they want PWM for 280W - which means running a beefy cable or limiting future expansion options because of cable not beefy enough - and if they want something "automatic" that won't require any manual intervention, and if they want a monitor, and not just "a monitor" but a Tri, then... well, then this is what they will have. And it will work. Perfect - no. Nothing is.
