General RV Solar Questions?
I'm planning to add a couple of new high end Kyocera 140 panels and build up a new system out of them. Currenly I have what my old 95' Squire 400 came with which is a substandard and smaller panel wi...

Hi,
Here is a simple flow chart.
Budget-->Energy Audit-->Battery bank size-->number of watts-->PWM or MPPT. What ever type of controller is chosen, make sure it has adjustable set points and a temperature probe that is on the battery.
One rule of thumb is between 60 and 150 watts of panels per 100 amp-hours of storage. The smaller the battery bank the higher the wattage needed (per 100 amp-hours).
If you do your homework, there is no need for a Trimetric type meter. If you feel you MUST have one then go for the Victron meter as it makes a more accurate "guess" than the Trimetric.
I'd prefer to spend my money on panels or a good controller.
On an entirely different note--inverters may be quite "noisy" in the radio frequency spectrum. You may need to use some chokes to help--or even use some shielding around the inverter. The RF interference goes up seemingly by the cube of the power being drawn.
