heres some of the stuff of what i have for the solar/power system.
A typical off grid solar panel generator requires solar panels, DC disconnect, charge controller, battery bank & system meter.
Panels: kyocera KC 130TM $450
Disconnect: Outback PV array 20A-125V DC breaker $16
Charger Controller: MPPT-20 $89
Battery: Trojan 24 TMX 12V 85Ah group 24 flooded deep cycle battery $135
(i hope 85Ah will be enough)
System meter: Trimetric TM-2025 12-48 Volt battery monitor system $150
The total of these are right now is $840 which is alot. Right now i'm trying to figure out is how to make some of these things our selves. With the charge controller i'm trying to find out how to charge a battery safely and using MPPT(maximum power point tracking) to store the most power. If we incorporate MPPT, it will allow us to use excess voltage from the pv to charge the battery with more efficienty instead of wasting that extra power.

Justin,
ReplyDeleteA couple of things:
1. The battery size needed is roughly 400 Amp-hrs
2. The charge controller and monitoring system is to be designed by the electrical engineers and not store bought.
Thanks for the work.
