Check out the Wattmon <http://wattmon.com> for simple off-grid remote system monitoring.
We have been impressed with the simplicity of it and the quality of the data it produces. Of all the systems I have tried, this one is my favorite so far. We are integrating it into our pre-wired off-grid MicroNexus power centers to provide data logging and remote communications. The only real limitation with it currently is that the hall effect sensors that are used to measure DC current between the PVs, the inverter/charger and the battery are too small for standard NEC required wire sizes for that equipment at standard US power levels. (i.e. 2/0 or 4/0 wire) It is designed and made in India and marketed to the micro-scale SHS market there. #6 THHN is about the biggest wire it can take. We are working with them on newer version for the US market that will have larger hall effect sensors, up to 4/0 battery wire. They are building a first batch for us now. Let me know if you are interested in purchasing any and we can combine orders to save on shipping.
