\n fuse & peak protection <\/div>\n

\n Protect drivers from tripped fuses and peak tariff spikes <\/h1>\n
\n

Monta watches total household load and holds charging below both the fuse limit and the driver\u2019s peak threshold – automatically, without interrupting the charge.<\/p>\n <\/div>\n

Two problems. One meter integration. <\/h2>
\n Both address separate issues caused by unmanaged EV charging alongside other household loads – and both run on the same whole-home measurement as SolarCharge, so one hardware connection serves all three.\n <\/div>\n <\/div>\n \n \n

Fuse Protection<\/h3>\n

\n
\"\"<\/div>\n<\/div>\n
\nRun a charging session alongside a dishwasher, oven or heat pump and the main fuse can trip, cutting power to the whole house. Monta measures total household current and slows charging before the limit is reached.\n<\/div>\n<\/div>\n\n <\/div>\n <\/div>\n <\/div>\n

Peak protection<\/h3>\n
\n
\n
\n
\"\"<\/div>\n<\/div>\n
\nUnder a capacity tariff, part of a household\u2019s monthly bill is set by its single highest consumption peak. One unmanaged session at the wrong moment sets the cost for the whole month. Monta holds total load below the driver\u2019s threshold.\n<\/div>\n<\/div>\n\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n\n \n \n<\/section>\n\n\n

From connected vehicle to smarter charging\u00a0 <\/h2>

No hardware to install. A vehicle connects once and the data works across charging, billing, and reporting.<\/p>\n

Ready-by still holds<\/h4>\n\n

The driver\u2019s \u201cready by\u201d time and target charge level still hold. Monta optimises around the goal, not against it<\/p>\n\n <\/div>\n <\/div>\n <\/div>\n \n <\/div>\n <\/div>\n <\/div>\n\n<\/section>\n\n\n

\n
\n
\n

How it behaves<\/h3><\/div>\n
Charging slows automatically and the driver is notified \u2014 infrequently, and only when Monta has acted. The limit covers total current across every charge point in the home, not each one separately. The charger always receives the lowest of the solar, fuse, and peak limits, so the features cannot work against each other.<\/div>\n<\/div>\n<\/div>\n<\/section>\n\n\n

\n What your drivers need <\/h2>\n

One meter connection serves fuse protection, peak protection, and SolarCharge \u2014 but not every device supports all three. Check the table before committing.<\/p>\n<\/div>\n <\/div>\n

\n

CT clamps fit at the main supply and must be installed by a qualified electrician, while meter readers are driver self-install \u2014 scan a QR code or enter the serial number. German readers (Powerfox, Stromleser) are the exception: by product policy, they support SolarCharge only, not protection.<\/p>\n\n <\/div>\n <\/div>\n<\/section>\n\n
