RE: Better AC filter for those who havnt seen it yet

if I had ducts, I'd have rvairflow that smooths air flow in the plenum and also smooths/increases the intake area https://rvairflow.com/pages/the-details

RE: Old automotive battery charger question

ye ole manual charger will bring the sg into the GREEN, ye newer ones won't. ye ole manual charger is used to power 12v items that come with alligator clips or cig lighter, ye newer ones won't.

RE: How to boost charge AGM batteries in storage?

Maintenance not in use. I think I need a Mex to English translator. maintenance - not in use, not being discharged, stand by. in use - being discharged or used!

RE: Solar mppt controller, uses for "load" outputs

With all the lighting controls for the load terms, program the controller for on a couple of hours and wire up LEDs under the trailer so it GLOWS for a few hours at sunset :B I've done this for years with 100w/motorcycle batt and 6 landscape lights around my deck. useless to me on the trailer.

RE: Follow up Solar Question

I'd fuse a 20A CC with a 20A fuse! or a 40A CC with a 40A fuse. wires sized bigger than the fuse.

RE: slightly different solar qx

controller eff of mppt is a real loss of power via heat sink, esp cheaper models! mismatched or in low power conditions. While I can't speak to some of the off brand/cheaper models of MPPT controllers, for the reputable ones (think Victron, Morningstar) the conversion efficiency is really pretty good. In the figure below, the orange line is a Morningstar MPPT controller, they don't say which controller the blue line is. In either case the power lost to heat is much lower than the power gained by MPPT and reduced wire losses. Victron's whitepaper and the graph 7.2 Absolute performance as a function of temperature (~page 10) convinces me with my various small 100w systems that mppt was a waste of my time locally in the heat. Their little blue shaded area is actually wider than they suggest! 7.2 Absolute performance as a function of temperature https://www.victronenergy.com/upload/documents/Technical-Information-Which-solar-charge-controller-PWM-or-MPPT.pdf graph assumes mppt has higher voltage to continue to 'buck'. :E

RE: Advice on new RV battery maintenance.

If always followed this advise "The chargers should always be connected to the same points as the loads. Without exception." http://www.smartgauge.co.uk/batt_con.html

RE: Bluetooth Adjustable Converter?

Been 8 years since I set my solar controller. Have not even looked at the settings since. so you used software (app) and a cable connected to a computer to do this? I did this with BT & phone once, seemed simpler than piss anting a laptop to the garage and finding a cable.

RE: Using RV generator as backup for house?

I use a generator interlock https://www.interlockkit.com/ https://www.geninterlock.com/ it is manual, installed a 30A 240v plug, an adapter ties both lines together with a 30A TT plug witch can use an RV extension cord to 120v generator. This allows me to operate the gas furnace's fan and any 120v circuit that I flip ON. At a later time I can obtain a 240v generator big enough for the air conditioner/dryer/water heater!

RE: Math is Hard-- C Rate ?

CA clearly means charging current as seen in the charging graphs. Capacity is shown in % (% of C), makes graph generic. the math has never been correct since a % of ah is not equal to amps. these folks introduce CA = % of C in amps (charging current) Which means .2C (amps) = .2CA (amps) .2CA = 20% of C (capacity)in amps Nothing new here

RE: Floating vs Storage Voltage Question

JCI in this ole spreadsheet shows 12.9-13.1 float forever! the tab at the bottom "Marine Battery charging" https://docs.google.com/spreadsheets/d/1csYoEciHDwUL2wxRO65H3Vj8gGdA8Paiw_Y-HcIvBBE/edit?usp=sharing I've always thought of float as a voltage that neither charges nor discharges, Mex has talked of floating his 31AGM for years that maintains capacity.
