The New Mini Magnum Panel (MMP)

The new Mini Magnum Panel MMP is an inclusive, easy-to-install panel designed to work with one Magnum MS-AE, MS-PAE, MS, RD or other non-Magnum inverter/charger.
Features:
  • Small footprint: only 12.5" wide X 18" tall X 8" deep
  • Money-saving design: not only is the MMP less expensive, but it is pre-wired for fast installation, saving labor costs
  • Easy access: front-mounted breakers and remote (optional)
  • Choices: can be wired for 120 VAC or 120/240 VAC output
Includes:
  • One DC breaker - 175A or 250A
  • One AC bypass breaker - 30A dual pole or 60A single pole
  • 500A/50mv DC shunt
  • DC busbars for battery positive and negative
  • Din rail for optional DC mini breakers - will hold up to six batteries

Solar On the White House

Solar panels and solar hot water heater on the roof of the White House. Its an excellent idea and we agree with most people who think it sends a powerful message about renewable energy in the U.S. However, if congress doesn't pass new legislation and states hold back on providing more incentives for those of us interested in providing Solar Energy and using Solar Energy, then the country is not practicing what its preaching and a little hypocritical.

The database for renewable energy incentives is always being update and a good go-to source to find incentives in your area.

Dry Battery Activation (Lead Acid)

Activating a Dry Charged Battery
Special order Rolls Batteries can be shipped dry (acid shipped separately or bought locally). To activate these batteries, start by removing the vent caps. Using approved battery grade electrolyte (1.265), fill each cell half way between the plates and the bottom of the vent well tube. It is important not to over fill the cells as the acid will expand upon charging. If the cells are too full, the acid will spill out of the top of the cells. Allow electrolyte to saturate into the plates and separators for at least 90 minutes. The temperature of the electrolyte will rise and the specific gravity will drop. Once this is complete, place the batteries on charge at the finishing rate (5% of the 8 or 20 hour rate). The rate may be increased if the battery does not begin to gas. Do not let the cell temperature exceed 115F (46C). If the temperature becomes excessive or the cells begin to gas vigorously, reduce the rate of charge. Continue charging until the cell (or cells) reaches within .005 points of the specific gravity of the filling electrolyte corrected for 77F (25C). We recommend to continue charging for an additional 60 minutes to insure no further rise in specific gravity.

Top up or remove electrolyte as necessary for proper level. Never add electrolyte (only approved water) after activation. Replace vent caps and remove any spillage of electrolyte. If necessary, clean with bicarbonate of baking soda and water (100 grams of soda to one litre of water). Rinse with water and wipe dry. Ensure that the soda solution does not get into cells.

** Do not place batteries on charge until electrolyte temperature is below 35C
